====== CV-1 ======
CV-Recorder/Looper & CV-Generator\\
Control Voltage Recorder, Looper, and Generator - for a own Eurorack-Line... more in Future!\\
{{:phatline:CV1-Case-Proto0.jpeg?500|}}\\
--this picture is the first prototype - pre-Eurorack :-D
[[https://youtu.be/pwgeu4ws50o|very-early-version...k]]
===== Features =====
 * A Envelope which can be Recored from an AIN-Source, it can be Editet on Startpoint,ATK-Playbackrate, Decay-Playbackrate\\
 * LFO which Waveform is stepless morphable from Sine Square Tri Saw-Up to Saw-Down...(only Clocksynced!)\\
 * MSQ MotionSequencer to loop a CV-Signal.\\
 * A Mixer Page which Mixes/Mutes ENV+LFO+MSQ - and scales the output CV\\
 * Copy, Paste, Clear: to Transfair the CV Sequence to other CV1 Instances\\
 * 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 ======
**Midibox:**\\ 
  * [[http://wiki.midibox.org/doku.php?id=dipcoref4|dipcoref4]] - this is the µC Brain for CV1\\

  * no other PCBs needet - but expandable with other Eurorackmodules in Future\\

  * µSD-Card, formated with FAT32\\
  * Soldering Iron - with a Dip that can Handle SMD-Parts, Wires, solder Paste for the µC....\\
  * Eurorack Power Source +-12V AND +5V!\\

==== Set ====

== Cabeling ==
Midi IN1 >>> CV1 Remote Device or a Midi-Sequencer\\
Midi OUT >>> to a Global CV1 Remote Device FIXME - which will need a lot of Midiinputs [[http://wiki.midibox.org/doku.php?id=m16|M16?]]\\

  * @JMidi1: connect your Sequencer to get Midiclock and Programchanges\\ 
  * @JAIN1: 2 CV Inputs - 12V tollerant\\ 
  * @JAUT3: 1 CV Output - (internal DAC with Protection Cirtuit > 12V Tollerant)\\
  * @J19:Get up to 8 CV-Outputs, with a [[http://wiki.midibox.org/doku.php?id=aout_ng|AoutNG]]\\
  * @JLCD1: up to 4 Additional OLED-Displays for every one a Reset Line - so no additonal Circuit needet\\
  * @J89: DIN and DOUT Shiftregister Chain: thought for decidet Expander Modules (which will come in near future\\
  * @J2/Bootload: If the core is not starting up - because of bad-Firmware, then bridge this Jumper to come into the Bootload-Mode\\

====== Software ======

===== Firmware =====
yes it loopin... but not good enough to release anything...

====== Building ======
The Design is optimized for Pick and Place most SMD Parts are on the Top-PCB\\
i ordered 5 PCBs from JLCPCP with almost all SMD Parts (except 10pF µSD and 4x100nF) presoldered\\
now waiting for Presoldered PCBs LOL - for 15€ a Piece!\\

===== To Do =====
a housing/case or frontplate\\

===== Resources =====

====== Community users working on it ======
  * **[[Phatline]]** =  Programming, Documentation...\\

Just let a Private message on the forum to user already involved.\\
I have ProtoBoards here - i test one, and if it works, i can share them for Beta Testing-if you pay the postage\\
