* [https://github.com/elkayem/midi2cv elkayem midi2cv GitHub page] - Nano based project
 
** Arduino MIDI library has '''not''' yet been ported to Pico so will need to use Python
 
** Drives 4 CV outputs: Pitch Blend, Control, Note, Velocity
 
** This card only drives Note (Voltes/Oct, Mod)

=== Other Notes ===
 
 
 
==== Daughterboard Heights ====
 
 
 
* From notes on [https://www.youtube.com/watch?v=HMDGYm91Q1Y How to Make Great Looking Modular Front Panels - Part 3 Module Circuit Board Layout]
 
** The absolute maximum of other boards I've seen is 111,5 mm and the TipTop Happy Ending Kit offers a space of 112,5 mm
 
* 114.8mm measured between 3U Synthrotek rails
 
** 128.5mm - 114.8mm = 13.7mm both sides, 6.875mm per side
 
** 111.5mm daughtercard, leaves 8.5mm clearances top/bottom
 
 
 
==== Part Orientations ====
 
 
 
* For pots with built-in pointers, pot pins go down for pointer to go up at center point
 
 
 
==== Front Panel Jacks ====
 
 
 
* [[Eurorack Panel Jacks]]
 
 
 
==== Eurorack Vertical Pots ====
 
 
 
* [[Eurorack Pots]]
 
 
 
==== Op Amps ====
 
 
 
* From [https://www.apogeeweb.net/circuitry/TL084-op-amp.html#tl084-vs-tl074 this site]
 
** The TL084 Op-Amp is very similar to TL074 but has high noise immunity and better offset characteristics.
 
** The TL074 has lower noise figure, so is better for AC signals.
 
** The TL084 has lower offset, so is better for DC signals.
 
** The TL084 has better DC performance (low offset) and the TL074 has better noise/distortion performance.
 
** '''You can use TL074s on the audio paths, TL084s on the control paths.'''
 
** [https://www.ti.com/lit/ds/symlink/tl071h.pdf?HQS=dis-mous-null-mousermode-dsf-pf-null-wwe&ts=1666712437480&ref_url=https%253A%252F%252Fwww.mouser.com%252F TL074 Datasheet]
 
** [https://www.ti.com/lit/ds/symlink/tl082m.pdf?HQS=dis-mous-null-mousermode-dsf-pf-null-wwe&ts=1666740012859&ref_url=https%253A%252F%252Fwww.mouser.ca%252F TL084 Datasheet]
 
* The TL074 is $0.75 in qty 10 ([https://www.mouser.com/ProductDetail/Texas-Instruments/TL074CN?qs=AMJt07B76uv7dLYnj7iLiQ%3D%3D on Mouser])
 
* The TL084 is $0.55 in qty 10 ([https://www.mouser.com/ProductDetail/Texas-Instruments/TL084CN?qs=q2XTDbzbm6ANF36GVAxPiQ%3D%3D on Mouser])
 
* The TL072 and TL082 are both about the same price as each other, but are more expensive than the quad parts
