Using OpenDeck to forward MIDI data to hardware Synth #15

Closed mungewell closed 5 years ago

mungewell commented 5 years ago

Hi, I am trying to understand how/whether OpenDeck can be used to forward USB MIDI to it's DIN output, and onto a hardware synth. I want to go: PC--USB-->OpenDeck--DIN-->Synth

I think that this is related to the MIDI merge interface control: https://github.com/paradajz/OpenDeck/wiki/SysEx-Configuration#midi-merge

On my Ardunio Pro-Micro hardware I have tried setting this to 'DIN out' (which didn't seem to output) and to 'OpenDeck Master' (which gave error code '0x0A' - guess that's not in the f/w I have on device).

Am I heading in the right direction? Thanks, Simon

Hi, no, in Web configurator you only need to enable DIN MIDI and leave merging disabled. Merging is used for when you want to forward incoming DIN MIDI data to DIN MIDI out, USB, or both. Also make sure you are using the latest firmware.

Hmmm, I think that was what I had previously seen (with #11) but doesn't seem to work now.

Either I am being an idiot, or perhaps my hardware is faulty. The current hardware was not working with the 'general' tab in the configurator and I was having difficulty reflashing it. The current f/w revision was reported as

00000000  f0 00 53 43 01 00 02 00  03 03 01 00 00 f7        |..SC..........|

I'll try to flash another Ardunio and see if that works for me. Thanks.

That tab doesn't work anymore with any firmware other that >3.1.0 as explained in the blog post: https://shanteacontrols.com/2018/11/19/opendeck-sw-v3-1-0-presets/

Also note that Arduino boards require certain resistors for DIN MIDI in/out as mentioned here: https://github.com/paradajz/OpenDeck/wiki/Hardware#arduino-pro-micro-3

As far as I understand Pin1 (tx) and Pin2 (rx) are used to transmit and recieve midi image Here is schematic.
