PD Space Guitar Synthesizer Forum

The preset manager is visible on screen allways on ipad in standalone mode.
On iphone or when used as an AUv3 and the plugin window is small, the preset manaqger is hidden untill you click on the <presetnamehere> - PRESETS button.
In the AUv3, making the pluginwindow bigger will automatically switch to the standalone layout with preset manager allwyas on screen.

The presetname can be changed here. (note: the name is only stored once you've saved it)


LATENCY chooser.
A normal setting for guitar is 20%. If you dont play lower chords, you might like to set it to 10% for faster playfeel. For bass guitar, you might set it to 35%, it will then sound clean on the low E. This knob does *not* alter the CPU usage in any way, in contrast to the buffersize setting in the audio config!

SAVE AS
clicking here will bring the manager in save mode: you simply then click on the presetknob where you want the current preset to be. The presetmanager will only save presets in the USER bank, so if you are in FACTORY bank, it will show automatically the USER area to save your preset in.

SAVE
clikcing here will safe the current preset. If the current preset is a factory preset, it will behave like "SAVE AS", and show you the USER banks to pick a spot for your preset. Factory presets can not be overwritten.

++IMPORTANT NOTES++

• the USER preset bank is not overwritten when the app is updated. Only the factory updates come fresh with any update of S
• the USER presets of the standalone and AUv3 are different. You can not safe a preset in the standalone and use it in the AUv3, and vice vers. This is due to the rather complicated security system apple employs, it is on the list for future implementation.

the REMOTE tab has 3 assignable channels to remotely control lots of parameters in PD Space Guitar.
AUv3 users: Please note that these parameters are not exposed otherwise to the host!
The assignable channels can have ENV as input source (your normal guitar sound): this means that your picking strength can steer the fx.
ENV2 uses the second channel of your interface, (it will just not work when only 1 channel is chosen for input, no harm done however)

The 3 assignable remtoe chanels have on to
<DESTINATION> chooser with 14 options available here
ENV/ENV2/CCx source chooser with 14 options available here
The sliders can also be used manually, but as soon the source generates data it will ofcourse be overruled. So



WHAMMY  -

• MAX SHIFT - The shift is summed upon the normal shift that is determined by OCT and PITCH.
• MARGIN -This will ignore a certain percentage of your footpedal's range at the heel and toe. This assures that your guitar will sound in tune. More extreme settings will make this a pitch switch instead of a glide

HOLD  -

• HOLD - the knob on the bottom is the master hold switch: it can work like a normal piano hold pedal
• Auto Hold Level - whenever HOLD is activated, this determines the level at which the hold buffer will be refreshed with new sound. For a new sound to be detected, the attack has to be more than 100mS. this is to ensure that pickattacks and noise are not sustained
  Regardless of this setting, the buffer will fill at each press of the HOLD knob.
  Just turn Auto hold Level at 30dB, and it will never fire.
  **PLEASE BEWARE**: using Auto Hold, requires clean in tune playing without glides and bends, otherwise the none chromatic content of your guitar's sound will slip into the hold buffer!
  
• Decay - The decay time of the hold signal
• Damping - Often it is unnatural to have the higher frequencies sustained that long. A higher setting here will shorten the life of the higer frequencies in the holdbuffer.

the Cabinet and Reverb are 2 IR engines (IR = Impulse Response)
They are stock material and not highly optimised. When used an a plugin, using a reverb in your host is mostly preferable. In standalone mode this concern is ofcourse less pressing, however if you're set on getting the lowest possible latency, you might want to turn at least the reverb off ( the cabinet does shorter IR's, and uses less CPU



CABINET - turn the speakersim on
LEVEL  - mixlevel
the dark button is clickable an opens a popup to choose from a list of speaker IR's

REVERB - turn the speakersim on
LEVEL  - mixlevel
the dark button is clickable an opens a popup to choose from a list of reverb IR's

The MOD tab contains 2 effects, that work with time
You cannot view this attachment.

MOD - the centered label is also the on/off switch of this modulator
BLEND - mixes the dry signal with the modulated signal. The mix of 50% gives the most rich sound.
FREQ - speed with which the modulator delay changes.
DEPTH - how much time the modulator is using at the max.
STEREO - makes it stereo by altering the modulation phase between left and right.
FEEDBACK - feedback in a delayed signal leads to colorisation, which with changing time constants leads to a bit of caleidoscopic flavour.

DELAY - the centered label is also the on/off switch of this delay
LEVEL - mixlevel
TIME - delay time in milliseconds
FEEDBACK - determines how many repeats you get
TONE - a bandpass filter to colorise the delayed tone..
Q - ..the severness of this colorisation. Keep  this at 0 for straight delays. the colorisation is incremental with every repeat of the delay: this is used to get a bit of oldschool delay flavour

MOD->DELAY signal order: first modulate, then delay
DELAY->MOD signal order: first delay, then modulate[/b]

To avoid confusion at forehand: this is not claiming to be a "normal" guitaramp!
It is an easy to use "MULTIMODE FILTER-LIMITER-WAVESHAPER".
For guitarsynths, fullfledged tubeamp emulations are often too thick, the aim from this amp is to be fully transparent when needed: the polyphonic waveshaper can create a lot of extra harmonics, the amps should be able to handle this without adding too much extra.

SINGLE / DOUBLE / QUATRO chooser
SINGLE mode mixes the normal guitar with the shaper into a mono signal before feeding it into a stereo fx/amp setup. (The Shaper blend knob is placed before the amp here)
DOUBLE mode has 1 amp for normal guitar and 1 amp for the shaper. the 2 voices of the Shaper share 1 amp here. The SPREAD knob places the amps in the stereo image.The shaper blend knob works on the amp outputs here.
QUATRO both normal guitar and shaper have a stereo amp. The 2 shaper voices have a separate and normal gutiar has 2 amps. Note that teh MOD fx can make the mono guitar pseudo stereo before it enters the amps. Again, SPREAD place the amps in the stereo image.

BANDPASS / LOWPASS / HIGHPASS FILTER chooser
A multimode filter with auto mode: The ENV/CC chooser to the right choose the source of automation.
The SENSE is used for setting the sensivitiy for the ENV/ENV2 sources.
ATTACK is the speed of reaction.
SWEEP FREQ to the left is the default cutoff/center frequency, FREQ to the right is the max possible frequency when the ENV/ENV2 goes higher.
Autowah / Envelope filter is achieved by using ENV as source, using a bandpass filter with positive gain (e.g. 20dB) and a bit higher Q (e.g 2), SENSE on 25 or above. Set SWEEP FREQ to the desiered colour at rest, set FREQ to the max frequency desired. Tweak the knobs for a nice playfeel.
WAH PEDAL is the same as autowah, you only swith the ENV chooser to a CC at which your attached midi footpedal is sending.


LOW CUT - highpass filter, the displayed numbers are midinotes. 28-Bassguitar low E', 40-guitar low E. Note that for leads, often a very high LOW CUT is used in productions, to focus the guitar more into a violin range. Same goes for acoustic guitars!
MID - this 800hz "mid scoop" is a typical feature of electric guitaramps.
SWEEP GAIN - A parametric sweeping EQ..
SWEEP FREQ - ..with its center freq. Again: midi note display.
TREBLE Cutoff the hight frequencies. This filter is placed *after* limiter and overdrive!
GATE - A simple noisegate
GAIN - GAIN pumps up the volume until it limits, so this is also a 1 knob sustainer
OVERDRIVE - Symmetric waveshaping clipper, adding odd harmonics.
SQUEEL - Assymetric waveshaper, adds even harmonics.
ATTACK - Automically adds smooth attacks when you silence the guitar a bit before plucking a new note. this is the classic mono version of the polyphonic ATTACK knob in the shaper: it is however not obsolete because of that. A classic attack knob like this is sometimes more suitable, especially for legato playing.
TONE - Using a more elaborate setup, this knob can roll of the overdrive grain at 6 dB per octave, while rolling of the guitartone itself at about 3 dB.

COMP->DRIVE - in this mode you get the max sustain with a more constant edge of the overdrive
DRIVE->COMP - in this mode you get more dynamics with a more dynamic edge of the overdrive

First tab is SHAPER
You cannot view this attachment.
BLEND -  blends the dry guitarsignal with the synth signal: the output is send to the AMP
TRESHOLD - this is not a normal gate, it is a spectral gate, meaning every frequency component indivdually has to cross the treshold to be heard.
ATTACK - this knob can slow down the attack, again for everyfrequencycomponent independently
OCT - pitches the whole spectrum in octave steps
PITCH - pitches the whole spectrum in halfnote steps
DROP - splits the spectrum into 2 parts: the lower part is dropped ("lowered") 1 octave. There is a 1 octave transition zone to provide smoothness at the drop border.
DOUBLER - The doubler has 3 modes:
1) DOUBLER  - The Doubler knob has fifths and octaves with varying degrees of detune.
2) OVERTONE  - The X knob chooses the overtone.
3) Harmonisers (12 keys)  - The HARM knob chooses from a ascending range of chordal notes within the current key. The chord range is a simple root-third-fifth structure.
-The MIX knob allways rules the volume of this extra voice.
-The positon in the stereo image is determined by AMP SPREAD and the stereo setting there.
-Setting AMP to QUATRO will give the doubled voice a separate amp! In DOUBLE mode the 2 shaper voices share 1 amp, in SINGLE mode normal guitar and shaper voices are mixed mono before being fed into 1 stereo amp. ( See the AMP manual page for more about this)



Now we get to the additive synthesis part:
HX OFF - no extra harmonics are added. You basically hear a representation of your normal guitar.
SAW - adds all multiples of the source frequency components.
SQUARE - adds odd multiples of the source frequency components.
BRIGHT - adds even multiples of the source frequency components.

The level of the added harmonics are ruled by a filtering scheme:
LP  - (Low Pass) the harmonics are added from 0 up to the cutoff frequency.
HP - (High Pass) the harmonics are added from cutoff frequency onward.
BP  - (Band Pass) the harmonics are only added around the cutoff frequency.

+ORIG The filterschemes above can mute the sound. If you want to allways have the original frequencies in the output, this knob will do just that!

SENSE - the sensitivity to the input: high sense will move the cutoff from MIN to MAX
ATTACK - the SENSE envelop can be slowed doen here to create interesting attack filter effects.
MIN - this is the rest position of the cuttof. If SENSE is 0, this will 100% determine the cutoff position. (Note that REMOTE/Filter uses this as min too!)
MAX - This is the MAX position which can be reached by SENSE. (Note that REMOTE/Filter uses this as a max too!)
RESONANCE - In LP and HP mode, this determines the height of the bulge at the cutoff frequency. In BP mode there is only this bulge, so it will work there as a pure volume for the filtered harmonics.
TONE - The added harmonics can be much brighter than your guitar. Therefore this knob can tone down the synthy sound. Note that the +ORIG knob's original spectrum contribution will be not affected by this. This means you can have bright guitar, filled in by synth in the lower frequencies.


At last, but not least, there is the dynamic modulation section:
OFF - no dynamic modulation
TREM - a tremolo with depth DEPTH, speed FREQ. The ATTACK above 0 will postpone the effect on newly plucked sound. ATTACK below 0 will only use the effect on newly p lucked sound.
DETUNE - A detune with 1 octave max DEPTH. The ATTACK above 0 will start the note at a lower point to glide into the normal frequency. ATTACK below 0 will glide in from above.
VIB - a vibrato with depth DEPTH, speed FREQ. The ATTACK above 0 will postpone the effect on newly plucked sound. ATTACK below 0 will only use the effect on newly p lucked sound.

Preset 1, Fluteway to heaven
For those who missed the hint in the name

Got an anonymous feedback about being stuck in config screen:
If you are stuck in Space Guitar's config window (standalone), it is because the audio settings are not compatible.
This is like 99,9% of the case with bleutooth headsets.
The current beta version 1.3.41 does not ignore bleutooth audio, so you have to turn of the headset or bleutooth.

A little live jam with PD Space Guitar 1.3.42 BETA.
the adaptive rotor and amp attack give a great playfeel
