JASS, Just Another Synth...Sort-of, codename: Gemini (UPDATED TO V-1.0.1)
jass-v1.0.1( esp with midi fixes).zip
1.0.1-CHANGES:
- Fixed issues with midi routing, re the mode selector (mentioned below)
- Upgraded the midi mode "fetch" abstraction to be less granular
- Fix (for midi) so changing cc["14","15","16"] to "rnd" outputs a random wave (It has always done this for non-midi.)
- Added a midi-mode-tester.pd (connect PD's midi out to PD's midi in to use it)
- Upgrade: cc-56 and cc-58 can now change pbend-cc and mod-cc in all modes
- Update: the (this) readme
INFO: Values setting to 0 on initial cc changes is (given midi) to be expected.
JASS is a clone-based, three wavetable, 16 voice polyphonic, Dual-channel synth.
With...
- The initial, two wavetables combined in 1 of 5 possible ways per channel and then adding those two channels. Example: additive+frequency modulation, phase+pulse-modulation, pulse-modulation+amplitude modulation, fm+fm, etc
- The third wavetable is a ring modulator, embedded inside each mod type
- 8 wave types, including a random with a settable number of partials and a square with a settable dutycycle
- A vcf~ filter embedded inside each modulation type
- The attack-decay-release, cutoff, and resonance ranges settable so they immediately and globally recalculate all relevant values
- Four parameters /mod type: p1,p2, cutoff, and resonance
- State-saving, at both the global level (wavetables, env, etc.), as well as, multiple "substates" of for-each-mod-type settings.
- Distortion, reverb
- Midiin, paying special attention to the use of 8-knob, usb, midi controllers (see below for details)
- zexy-limiters, for each channel, after the distortion, and just before dac~
Instructions
Requires: zexy
for-entire-state
- O: Open preset. "default.txt" is loaded by...default
- S: Save preset (all values incl. the multiple substates) (Note: I have Not included any presets, besides the default with 5 substates.)
- SA: Save as
- TEST: A sample player
- symbol: The filename of the currently loaded preset
- CL: Clear, sets all but a few values to 0
- U: Undo CL
- distortion,reverb,MASTER: operate on the total out, just before the limiter.
- MIDI (Each selection corresponds to a pgmin, 123,124,125,126,127, respectively, see below for more information)
- X: Default midi config, cc[1,7,8-64] available
- M: Modulators;cc[10-17] routed to ch1&ch2: p1,p2,cutoff,q controls
- E: Envelopes; cc[10-17] routed to filter- and amp-env controls
- R: Ranges; cc[10-17] routed to adr-min/max,cut-off min/max, resonance min/max, distortion, and reverb
- O: Other; cc[10-17] routed to rngmod controls, 3 wavetypes, and crossfade
- symbol: you may enter 8 cc#'s here to replace the default [10-17] from above to suit your midi-controller's knob configuration; these settings are saved to file upon entry
- vu: for total out to dac~
for-all-mod-types
- /wavetable
- graph: of the chosen wavetype
- part: partials, # of partials to use for the "rn" wavetype; the resulting, random sinesum is saved with the preset
- duty: dutycycle for the "du" wavetype
- type: sin | square | triangle | saw | random | duty | pink (pink-noise: a random sinesum with 128 partials, it is not saved with the preset) | noise (a random sinesum with 2051 partials, also not saved)
- filter-env: (self-explanatory)
- amp-env: (self-explanatory)
- rngmod: self-explanatory, except "sign" is to the modulated signal just before going into the vcf~
- adr-range: min,max[0-10000]; changing these values immediately recalculates all values for the filter- and amp-env's scaled to the new range
- R: randomizes all for-all-mod-types values, but excludes wavetype "noise"; rem: you must S or SA the preset to save the results
- U: Undoes R
for-each-mod-type
- mod-type-1: (In all cases, wavetable1 is the carrier and wavetable2 is the modulator); additive | frequency | phase | pulse | amplitude modulation
- mod-type-2: Same as above; mod-type-2 May be the same type as mod-type-1
- crossfade: Between ch1 and ch2
- detune: Applied to the midi pitch going into ch2
- for-each-clone-type controls:
- p1,p2: (self-explanatory)
- cutoff, resonance: (self-explanatory)
- navigation: Cycles through the saved substates of for-each-mod-type settings (note: they are lines on the end of a [text])
- CP: Copy the current settings, ie. add a line to the end of the [text] identical to the current substate
- -: Delete the current substate
- R: Randomize all (but only a few) substate settings
- U: Undo R
- cut-rng: min,max[0-20000] As adr-range above, this immediately recalculates all cutoff values
- res-rng: min,max[0-100], same as previously but for q
- pbend: cc,rng: the pitchwheel may be assigned to a control by setting this to a value >7 (see midi table below for possibilities); rng is in midi pitches (+/- the value you enter)
- mod-cc: the mod-wheel may be assigned to a control [7..64] by setting this value

cc - Modes M, E, R, O
Jass is designed so that single knobs may be used for multiple purposes without reentering the previous value when you turn the knob, esp. as it pertains to, 8-knob controllers.
Thus, for instance, when in Mode M(pgm=124) your cc send the signals as listed below. When you switch modes, that knob will then change the values for That mode.
In order to do this, you must turn the knob until it hits the previously stored value for that mode-knob.
After hitting that previous value, it will begin to change the current value.
cc - Modes M, E, R, O assignments
Where [10..17] may be the midi cc #'s you enter in the MIDI symbol field (as mentioned above) aligned to your particular midi controller.

In closing
If you have anywhere close to as much fun (using, experimenting with, trying out, etc.) this patch, as I had making it, I will consider it a success.
For while an arduous learning curve (the first synth I ever built), it has been an Enormous pleasure to listen to as I worked on it. Getting better and better sounding at each pass.
Rather, than say to much, I will say this:
Enjoy. May it bring a smile to your face.
Peace through love of creating and sharing.
Sincerely,
Scott
