Polylogue is a polyphonic analogue synthesizer inspired by the workflows of the Korg Monologue and the Korg Volca Keys.
Features
Six voice polyphony with two oscillators per voice.
Each voice is fully articulated, featuring its own envelope generator, low-frequency oscillator, filter, and amplifier.
Five wave shapes per oscillator: Saw, triangle, square, cosine, and noise.
Wave shaping for all four major wave shapes: Saw and triangle waves transform to shapes similar to the Korg Monologueās fully transformed wave shapes, pulse width modulation for the square wave, and frequency modulation for the cosine wave. The saw wave transformation implements Formula 26 from Section 3.5 of Phaseshaping Oscillator Algorithms For Musical Sound Synthesis by Jari Kleimola, Victor Lazzarini, Joseph Timoney, and Vesa VƤlimƤki.
A resonant filter which self-oscillates.
ADSR-style envelope generator which can simultaneously target the amplifier, both oscillator pitches, and the filter cutoff.
Per-voice low-frequency oscillator with saw, triangle, square, and cosine wave shapes, which can simultaneously modulate both oscillator pitches and the filter cutoff.
The secondary oscillator can be offset up to two octaves up and down from the primary oscillator, as well as detuned about another two-thirds of an octave up and down.
Four channel mixer for adjusting the levels of the two oscillators, line in, and a feedback loop drive.
Sequencing with Critter & Guitariās Sequencer 3.
Unlike Pickmansmodel on Patchstorage, I can switch back to the Patch navigator and choose another Patch.
It did āfreezeā the Organelle the first time I loaded it, though.
Thanks for testing! I have uploaded a new version to Patchstorage which should install a four voice version of main.pd if it detects an Organelle 1. Please try again!
Only thing Iām having trouble with is saving presets. I can click Init, save a new preset, but when I close the patch, open it back up, and try to load a preset, it doesnāt seem to pull up the settings from the saved preset.
I managed to get it to kind of work a second ago, but not sure exactly how.
I think that making edits, and then saving a new preset will work, but if you try to intermittently save changes as you are designing the sound, it doesnāt seem to save.
Iām making use of KontrolModule by @thetechnobear, so itās a learning curve for me too, but I think I understand how it should work now. You can add and select presets through the preset menu (by selecting the default patch called Init) but you have to save them by selecting āSave Settingsā from the main menu in the patch (the last option, after MIDI learn). This last step will save the ārackā settings, i.e. the state of the patch from what I understand. You can then rename your presets by editing the file named polylogue-rack.json in the patch directory. Hope that helps!
Wave shaping! The previous releases only had pulse width modulation for the square wave. Now the saw wave transforms into a similar shape to the Korg Monologueās saw, as does the triangle wave, and the cosine wave has limited frequency modulation. Itās not an FM synth, but itās fun to play with.
Performance improvements. Each oscillator now switches off DSP processing when itās not in use. This has resulted in better CPU usage on the Organelle M. The Organelle 1 is still limited to four voices. Since I canāt test on the original, any feedback is appreciated!
Edit: I suspect I might have broken the LFO in this update but havenāt confirmed. I didnāt edit it, but it also uses the oscillators from the VCOs, and I forgot to update the LFO to also send a switch value to them. Will fix it this weekend!
Edit 2: Iāve fixed the LFO! Version 1.0.6 is now available at the links above.
Such a nice patch, really amazed by all the parameters !
the only issue is that the sequencer 3 donāt work on my Organelle 1 who is unable to read the sequence that has been recordedā¦ Iāve downloaded PD 0.49 and the first versions of Polylogue but the problem stay the same. (thereās also a parameter BPM that stay to 00, donāt know how to change itā¦). I have downloaded several other patches that uses sequencer 3 and the sequences can be read without problems. Thanks for sharing this patch however! Greatings from France
I am having the same issue on organelle 1. Really love the patch but I canāt seem to record or playback anything. sequencer 3 works fine with other patches. Any help would be greatly appreciated!
@Stlcody1@Amb - I think the reason itās not working for you is because of a minor difference in how the Organelle M and Organelle 1 handle Ableton Link.
The Organelle 1 looks for the Link code in each patch folder. The M has Link ābuilt inā to the OS. If the M finds one particular file (highlighted here)
