I don’t know why DM don’t work but I think it’s fine if some questions are posted publicly too. I will post more details and a FAQ section asap on Github.
There seems to be a certain interest for Midi so I’m considering adding a midi header to the next PCB. The current prototype is made for Midi over Bluetooth
At the moment it’s mainly WIFI and Bluetooth
Actually, the “concept” is to have a RPI Zero W powered by the Eurorack case, attached inside it, connected to the i2c bus and accessible only wirelessly via Wifi (OSC) and Bluetooth (Midi).
Powering a Pi Zero W from the 5V rail is OK but it becomes complicated when USB are connected to it and draw additional current…
That being said, it’s already technically possible to connect a micro USB hub to its usb host input and connect a Midi controller via USB. I tested that with a Pi3, outside of the euro case and with an external power brick and it was working. But this is not something I’ve worked on much because my initial goal was to get rid of all the cable (USB, i2C etc) going in and out of the case. So… it’s possible but it’s not made for that.
I have to say that the “hat” is only here as an easy and rather safe way to power the Pi from the Euro case and to put pull-up resistors on the software i2c bus but things can be done and connected without the hat too. It’s just that it’s more risky.
No, not yet unfortunately. But this is something I have considered and I’m considering again now. At the moment there are no DIN midi connections (yet) on this small prototype hat. The original plan was OSC to I2C and Bluetooth Midi to I2C only. “Wired” midi has been added only three days ago while adding Ble midi, this explains why the hat doesn’t have any IO for that yet.
It should be “easy” to add a midi IO header and circuit in a future revision, Edit > but this would require using the UART pins of the PI and this would probably affect the bluetooth quality :-/
Right now, the Pi doesn’t talk to Teletype, TT is a leader, like the Pi and they cannot read values from each other [^1]: . Do you mean Melisma => Teletype or Teletype => Melisma ?
Teletype to Melisma should be possible but this part of the code has not been developed yet. But there’s a second i2c bus ready for Teletype, I didn’t have time to try passing values from one bus to another…
[^1]: Hans converts OSC and MIDI and sends that to ii followers only (TXO, 301, etc) via i2C. Midi to I2C is handled with a custom JS midi map that needs to be edited. There’s no “default” map.
