All Parameters are saved as a preset as a song (programchange…)
Digital created LFO+ENV with CV-Output.
No Displays, No Menues, Minimal buttons, much Scopes, much Led-Ring-Rotarys (LRE-8x2CS)
one big UI with complete functions for one LFO+ENV Voice + 4xChannelstrip Controlls…
LFO+ENV are mixed together softwareside, to use only one CV-Output
Each Channel = Filter need 8xCV-Outputs
Copy Paste for LFOs and ENVelopes between the Voices
Copy Paste for a Song aka Preset aka Bank aka Program(change)
Jam Style Pattern load (next Preset Display) + Preset Morph between Current-Preset and Next-Preset
The Early Design was a EuroRack-Module: 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…
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.
-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):
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… would give no memory…
this will not be supportet > since i dont want a Euro-Module Setup > i want one big filterbox.
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 or as numeric Value?
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…
6.DRY-WET (Orginal vs Filtered Mixer)
7.Send 2 EFX1
8.Send 2 EFX2
So 1x 8AOUT-Module for each “Channelstrip”, makes a total of 4x8AOUT-Modules.
The Module of Choise is a 16Bit, since i control with the the same AOUT-Channel ENV+CUT-OFF…
so there is no analog potentiometer for Cutoff or resonance… it is all saved in the Preset.
the VCA is basicly a simple VCA (MS20Like) or something
the VCF are a 303 18dB for the 24db Filter it will be a SSM2044, where bords are available.
In order to not use those overprized MATCHED-PAIR-TRANSISTORS (over 2€ on the cheapest place) i have to use standart Transistors and make a VBE-MATCH on my own, i have already a PCB from here - to measure the transistors with a Multimeter: https://midisizer.com/other/vbe-matching/
The Panel is made of transparent but shadet (black transparent) Plexiglass.
The Panel is directly mounted into a Flightcase.
The 3x LRE8x2 (LEDRING) are mounted with the Encoder Nuts, the rest of the PCBs are mounted with normal thruhole screws.
The Analog-IO Board on the Backpanel, holds:
-the DryWet-VCAs, Filter-Releay-Switch
-the Summing Mixer
-the Connectors to connect the Filter, AOUT, Poti-Boards
