This is an old revision of the document!
Digital created LFO+ENV with CV-Output. No Displays, No Menues, Minimal buttons, much Scopes, much Led-Ring-Rotarys (Planed for LRE-8x2CS), one big UI with complete functions for one LFO+ENV Voice… switching between the UI-Voices is done from the BREAKOUTMODULES…to this later
LFO+ENV are mixed together softwareside, to use only one CV-Output
8xCV-Outputs (VOICES) are supported > if u are on a VCF+VCA-Setup = 4 Voices on the Analog-Side (4xFilterbank)
Copy Paste for LFOs and ENVelopes between the Voices
Copy Paste for a Songa aka Preset aka Bank aka Program(change)
Jam Style Pattern load (next Preset Display) + Preset Morph between Current-Preset and Next-Preset
A Breakoutmodule for each CV-Output, with Depth-rotary, Focusswitch (Pushrotary), 2x Scopes (LFO+ENV) and LFO/ENV-Switch to show on one Display the Mixed Waveform & to switch the Rotary to “ENV” or “LFO” Mode (there is only space for one Encoder - maybe just make PAN Style, instead of 2 individual level -maybe more live feel?, how ever when using an 3Stage switch, i could disable MIX-View, or display it on ENV or LFO…maybe a good choise ;) ) The Depth-rotary has no Ledring, want to display it as a bar or as Value in the scope…
Whole thing will not be compatible on MB-CV concepts… i will copy code snippets and so on, but i have to understand it from scratch… anyhow this is not generic
THE LEFT SIDE of the BRAIN > Preset-Management:
Save & Load the PROGRAM, can be done by Midi-ProgramChange -or With the LOAD-PRESET-Encoder
then press LOAD -or Morph to the next Program slowly with the MORPH-Encoder
-Another option is to take a PUSH-ENCODER for LOAD & STORE > and load and store it by pushing it… would free 2 buttons for other functions.
MORPH?:
-The Upper 7 Segment LED- Display: is the LOAD Display indicate the new Program with ENV+LFO
-The downer7 Segment LED- Dsipaly: is the STORE Display it indicates also the current Program with ENV+LFO
–with morph you crossfade between both Presets (be carefull, first Store the current Preset
Paste & Copy do their job @ the whole PROGRAM Memory
ENV-PASTE & ENV-COPY do their job @ the selected Envelope > (ENV-Voice selection is done by the breakout Modules) … LFO..same
Midi-Channel Note NR or Number of Envelope is a real programmer job (C), with usb-upload from computer
…. this is a individual device, and once set, it has to play > and it just should do LFOs and Envelopes
Fixed routed, no generic, special > in my case for a filterbank.
THE RIGHT SIDE of the BRAIN > LFO + ENV Settings (one Voice):
ADSR with:
CURVE Paremter which give exponentially to it (no straight lines While Fall and Rise)
Short: just shorten the Maximal lenght of a Envelope, haveing more Feeling on Encoders
should change Scope Display also…
LFO: get synced with Midi, and there is a retrigger by Notes…
Phase: offsets the start-Phase
Delay: simple delay (nte-Trig)
Rate: clear from 8 wholes to 128th or so
Wave: access to the Waveforms
Duration: interpret Midisync in trippled, whole notes or whatever…
DEPTH: is the maximal Value of FALL and RISE and SUSTAIN, i know i loose resolution with this…but i have to have a memory filterbank,…doing depth instead with Potentiometers on Filtermodules… is no memory…
1. Discharged UserInterface for the Brain in “Island mode” (Scopes + Digital-CV-Amount)
2. CV-Breakout EuroModule to be located near the CV-Destination (example: a Filter).
2 Waveforms (ENV+LFO) are mixed together softwareside
that bring 2 advanteges:
1.save one CV-Output
2. the Amplitude of each Waveform is saved in the patch, so the CV-Amount to a Filter is saved in the Patch
That bring 2 disadvanteges:
1.LFO or ENV cant get patched to individual destination
2.the Resulution gets lower 2 very low, and the code has to be adptet much… or have to be made from scratch
Because I use the device for a Memory-Filterbox (VCF+VCA), i am ok with the pros and cons, so i call it EASY-CV
Envelope Scope: show the ENV-Waveform
or the Mixed-CV-Output-Waveform (when Switch is in LFO Mode)
and show the Envelope-Amount with a BAR
MIXED CV Plug: CV-Output > Mixed Waveform ENV+LFO
Switch @ ENV:
Switch @ LFO: visa versa ENV
Press the Encoders built in ENCODER-BUTTON:
will switch the BRAIN-A-D-S-R and L-F-O ENCODER to the Page for THIS Module…
workflow, see what you have with a Scope, over a filter, and edit exact this selected CV on the brain in full detail…
THE VCA and the VCF are controlled with each one CV - each CV has a LFO and a ENVELOPE digitaly mixed… fixed in routing.
basicly a simple VCA (MS20Like) that drives the input of a Audio transformator 1:3 which is a Neutrik NTE10-3 (9€)
this “Tesla” Hi Gain - goes now thru the Post-VCA-Gain-Potentiometer - which then overdrives the 303 Filter (my prototype was a Freebase 383)
sound now goes to the Post-VCF-Gain-Potentiometer
now sound goes into a OP-Amp - to have the change for a light overdrive
From this point a EFX-Send Potentiometer send the Processed Signal to a extra Output (EFX-Send)
With the +DRY-Switch, we switch the orginal Signal additional to this EFX-Send-Potentiometer (or not)
Parallel to the EFX-Send Potentiometer is the DRY/WET Potentiometer it Pan between Orginal and Filtered Sound.
after DRY/WET come the Volume-knob and the Audio outs…
Fill with 303 mods take orginal VCA (have a bunch of this ICS) or make MB33 Style with standart components…
Here are 8Envelopeś 4xfor VCF 4xfor VCA… in fact there could be used more then this for example 8xVCF and 8xVCA…since the BREAK-OUT-Modules are Modular, and they share the same “Main-UI”…the only limiting factor is the CODE…i am not a C-Guru, and maybe i will still have timing problems with 8x CV-Outs…we will see.
I will use it to filter:
2xGuitar-Loopstations
1xGuitar
1xPercussion-Master
The panel size is 3U, Eurorack compliant
The Analog Circuits (VCF+VCA) get sandwitch as normal (not90° angeled)

- BRAIN PCBs:
a.Left-Brain
b.Right-Brain
- LRE8x2CS - is a generic PCB which i already have (fairlightiiś)
- BREAKOUT PCBs (maybe have to sandwitch because of shiftregisters and less space)
- FILTER PCBs (have to sandwitch)
