first synth i’ve “finished” (always hard to say when something is actually done), called the Best Friend - a semi-modular (kind of) taking some light inspiration from the Sequential P6, completely built with free modules.
here’s the full mess (yikes!)
simplified UI:
(along with some helpful notes)
sounds here - all made using the internal clip recorder in a single take (16 is the newest patch iteration fwiw)
https://soundcloud.com/best-friend-synth/sets/synth-test
features include:
-
3 VCOs, completely clean below 25% volume and begin to distort past 50% volume
-
2 morphing VCOs using Audible Instruments Macro Oscillator 2
-
1 standard VCO with selectable waveshapes using BogAudio VCO
-
distortion is using Vult Lateralus diode ladder filter (set flat)
-
Pan Spread of Osc 1 + 2 using Mockba ASSprdr - each OSC is opposite the other and moves inversely in the stereo field. Pan Unison syncs them.
-
-
Noise Generator using MSM Noise
-
Ring Modulator using BogAudio VCO + BogAudio AM/RM
-
selectable carrier (Osc 1/2/3)
-
selectable modulator (“Internal VCO” or external source)
-
lfo to audio rates
-
distortion using Mockba Tuube
-
-
Amplitude EG using VCV ADSR EG
-
Filter EG using VCV ADSR EG with assignable velocity per filter
-
HPF using Venom Multimode Filter
-
LPF using Nozoid 68_VCF_MOD
Semi-Modular section:
-
2 Aux LFOs using BogAudio VCO
-
2 Aux EGs using BogAudio DADSR(H) - each routed to the Aux LFOs (Aux EG 1-> Aux LFO 1, Aux EG 2-> Aux LFO 2) - [visualizers]
-
2 identical bays of Aux Ins with Depth Controls
-
1 bay of Aux Outs
-
1 bay of miscellaneous Aux Ins
Poly Pan:
this is a complex panning section that overrides Pan Spread, applied to Osc 1+2 (with Osc 3 being selectable). When using sine modulation each voice receives an output phase shifted 30degrees from the fundamental for swirling phase panning effects.
-
switchable between Sine using 3 BogAudio 8FOs and Random using 3 docB RndC
-
LFO Sync switches between one 8FO as the master control or each of the 3 8FOs running independently with frequency offsets set by the VoiceSpread control (8FO 1 to Osc 1, 8FO 2 to Osc 2, 8FO 3 to Osc 3)
-
Sync Voices switches between panning per voice or panning per Oscillator
Poly AM: [visualizer]
similar to Poly Pan but utilizing banks of random sinewaves using docB RndC controlling VCAs for slow amplitude modulation. Poly pan on/off must be turned on to activate Poly AM (although Poly Pan Depth may be zero of course)
- Sync Voices switches between AM per voice or “global” (Osc 1+2 and 3 if selected)
Global controls:
-
2 Distortion stages (both stereo)
-
(pre-filters) summing using a pair of Vult Lateralus diode ladder filter (set flat)
-
(post-filters) using Vult Debriatus wave destruction
-
-
Chorus using Vult Jorus analog chorus
-
Limiter using BogAudio LMTR
-
FM using BogAudio LLFO + BogAudio DADSR(H) for delay - [visualizer]
-
Warble (from Noise)
-
separate sutble Slop controls for V/Oct, EG/VCF and LFOs using 3 docB RndC + Grande Split8
-
Glide controls
-
Unison switches between polyphonic and monophonic key control
-
Velocity to V/Oct - adds between 0 to +16cents per voice based on velocity.
-
simple audio clip recorder using VCV record
Effects Send/Return using 4ms AuxSends:
-
Delay using Bastl Basil
-
Spring reverb using a stereo pair of Befaco Spring Reverb + Bacon Music SampleDelay for stereo width
-
Reverb using Valley Plateau
-
Sidechain compression of effects using Frozen Wasteland Manic Compression
other additions - mod wheel! (how could i forget that?), MIDI map (already added since writing all of this but it isn’t shown in the screenshot)
ideas on how to further optimize CPU are greatly appreciated - the most obvious answer here is to reduce the number of RndC but i would like to keep all of the variability.
any idea how to get a proper polyphonic/monophonic mode without using 2 separate instances of MIDI->CV? summing to an individual channel does not give the desired results.

to initialize poly/mono in MIDI->CV, set both of them to your MIDI device!
