PD Space Guitar Synthesizer Forum

First tab is SHAPER



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.

PRESERVE is for the shifter to preserve the original spectral shape, it is a simple "formant preserve" function. So if you shift down an octave, with hx off, preserve will make it brighter
ATTACK - this knob can slow down the attack, for every frequency component 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 SPREAD (see SPACE tab) 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.

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!
FOCUSmakes the tone darker, focused on the root note. It is for getting the low notes darker.
RANGE - a lowpass for the seeds going into the harmonics generator.
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 stereo 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

PD Space Guitar 2: what's new?
———————————————--
TUNER
==============
The tuning fork is allways there for you to tune your instrument: accuracy is 1%.
little nice feature: The ring on top of the tuner wobbles with the frequency you'd hear the wobble with the reference tone..

SHAPER
==============
-Now there are 3 doubler modes: Doubler, Overtones and... intelligent Harmonisers!
the harmonisers use a simple 1 3 5 chord expansion over multiple octaves and can be automated via remote / ENV, which results in a nice auto arpeggiating frenzy.
The harmonisers plays one note from the chord row on the doubler channel.
The TREM/DETUNE/VIBRATO section:
-Trem is stronger now.
-Detune
-Vibrato is now stereo, which is a great effect when attack is set to positive: it will make longer notes swim..

-there is now a CHROMATIC knob, that uses the tuning set in the SETUP tab

-The extra HX harmonics now have an inputrange RANGE: this works great to prevent getting too much overtones.

AMP
=============
the AMP now has a multimode filter, with remote/ENV oparation. Auto-wah or by remotecontrol and more.
Sensitivy adjustable with indicator on screen.  Wackawacka!
SQUEEL adds even harmonics
ATTACK a classic slow gear function: great to have your guitarplucks hidden

FX
========
The modulator now has a ROTOR mode. Note: the spread in amps governs the global pan width, so you have to adjust that too for best results! Let your inner Lachy Dooley out!
The delay now has multiple repeats and a tap tempo.

SPACE
========
SWIPE EQ - a fullfledged 11 band equaliser with frequency response display. You can quickly draw a line over the knobs, hence the name..
CABINET and REVERB where already there, new are:
AMP setup: SINGLE, DUO or QUATRO.  SINGLE is the old setup with 1 amp and stereo fx.

SETUP
========
FX setup: governs the processing order of MOD, AMP & DELAY
PSEUDO pseudo stereo can give big sounds with good mono compatibility.
LATENCY: added 5% for low latency voice application.
TUNING: determines the tuning for chromatic mode.

REMOTE
=============
Reworked the remote system: In he 3 free assignable channels, both ENV's and CC's now have sensitivity and direction.
A great number of hidden app parameters can be assigned to your playing strength or midi input.

Reworked the HOLD function: now with indicators on screen and easy to use level control

=======================
>>SPECIAL FEATURES:

1. MIDI PC is limited to 0-99
MIDI Program changes will be only work normally when in the range 0-99 (MIDI hardware PC number is 0 based, your controller may show 1-100..)

2. Small MIDI controller hack
MIDI PC's in range 100-109 (1 base controller: 101-110) will choose from the 10 current presets on SG screen. You only need to program your footcontroller's pedals once. This is ideal for MIDI controllers that have no bankswitch: e.g. you can have 4 switches with PC 100,101,102,103: These will engage the first 4 presets from the bank on screen.
Basically you can make a bank for your song, and the footswitch works as a songpart selector.
Bankchanges then ofcourse need to be done manually on screen.

3. Automatic Preset range clamping to current range
- An SG range is 100 presets
- incoming MIDI PC will clamp to the current SG preset range.
This allows for parallel changes in multiple SG instances, which is extremely usefull for doubleneck, stickplayers & stereo/hex setups.
E.g.: SG instance 1 is on 110, SG instance 2 is on 210
Now incoming MIDI PC 1 will switch SG instance 1 to 101, and SG instance 2 to 201
