CC-Looper
CC-Automation
Midi Control Change MotionSequencer - for Synthesizer with LEDRINGS
Features
* 4Midichannels @ each 512Steps X 32th-looprate X 128 CCs
* only a few of the 128CC should be used @ once - 4x128xCCs @ 32th is Midi Data MESS and µC Death
* maybe only 256Steps, will depend on RAM…. RealWorld will tell
* each TRACK has a shared Track length for all its 128 CCs
* Copy, Paste, Clear: for the all 128CCs/or single CC
* There is no EDIT, you can clear a CC or Track and make a new Take
* ProgramChange Load and Store on microSD-Card, Load and Store are CC-Commands, so you can remote the device
* The Sequencer can be set to Tact Systems: 3/4 4/4 5/4 7/4 9/4 11/4 13/4
Hardware Requirements
External Requirement:(for example)
- You need a Synth with LEDRINGs - otherwise you have no Feedback and Overview - NordRack III is such one
- Melody/Clock Source with ProgramChange-Output: midibox_seq_v4l oops that dont do PC…
- Melody/Clock/CC Destination: NordRack III or any other Synth with Visual Feedback off CC-States
Midibox:
- dipcoref4 - this is the µC Brain for the Looper
- cc-looper - this is the UI-PCB of the Looper
- no other PCBs needet
- µSD-Card, formated with FAT32
- Soldering Iron - with a Dip that can Handle SMD-Parts, Wires, solder Paste for the µC….
- USB Power Supply with µUSB-Connector
Set
Cabeling
Midi IN1 »> MelodySequencer and Remote Devices
Midi IN2 »> Midi Out from Synthesizer - which sends out the Moved CCs
Midi OUT »> Midi IN of Synthesizer input (Automated CCs merged with mididata from Midi IN1)

I have 10 ProtoBoards here - i test one, and if it works, i can share them for Beta Testing-if you pay the postage
