I’ve been unable to get the 201 to connect over usb midi.
I haven’t tried Din yet (need to get a midi a adapter)
Ive checked and saved the settings file.
Ive tested it out on several devices
A Windows computer
Polyend tracker mini
Presonus atom sq
Expert sleeper’s fh-2
Elektron digitone
Using the usb A port
Assuming im missing something
Any help?
It is recommended that a USB MIDI device is connected after powering up the 201. Then relaunch the main patch by pressing and holding the high E, F, and G keys and then press Shift.
yeah i’ve been doing that every time. same process as relaunching after leaving disk mode right?
There are two separate functions:
…the first combination (reload mother) is the one you want to use for getting MIDI started.
RE: connecting to other devices, how are you doing that? 201’s USB-A to other devices’ USB-B port?..USB-MIDI adapter?..or something else?
Oh yeah i reload the mother patch after i get out of disk mode. So then yes I’m doing it correctly it seems.
And im connecting via the usb A from the 201 into usb C into the other devices (the cable that came withthe 201)
You should not be entering Disk Mode while connected to devices other than a computer. Exiting Disk Mode is not a prerequisite for reloading the mother.
The 201 is a USB host. The Windows computer you mentioned is likely a USB host as well. The USB paradigm is Host —> Device, so you cannot connect two hosts together, unfortunately.
Do you know if the USB-C port on, say, the Polyend Tracker Mini is set up as a host or a device?
Does the Digitone have a USB-C port?
I am having a similar problem with my pocket piano 201 using the USB.
I am trying the MIDI connectivity with the controller OXI one (device mode), which use usb-c to USB A MIDI output.
While with same cable i can control the organelle M, seems that the pocket piano does not receive any MIDI message from the controller.
I checked the midi file setting of pocket piano and used the EFG + Shiftbutton to relaunch the patch but it seems not working 
Can you please suggest me something?
Thanks!
I’m not familiar with OXI One. But I see that OXI One has a TRS-MIDI Out jack - can you use that instead to connect to the 201’s TRS-MIDI Input?
Yes, with the trs mini jack the pocket piano Is receiving notes from Oxi. The problem comes using the pocket piano USB midi input.
Thank you for confirming.
We don’t have an OXI One to test on the 201. Are you trying to power the OXI One from the 201 using the 201’s USB-A port? This might be the issue - the 201 may not be able to power it.
Do you have another class-compliant device (no drivers needed) with a USB-B port (device) that you can try with the 201’s USB-A port?
Thanks for the support!
Unfortunately i don’t have another device with USB-B port to test with.
I just set the Oxi One as Device Self Powered. In this case the Pocket piano still doesn’t receive MIDI message by USB, but It happen a strange thing. If i play a note in the Pocket piano In the Oxi keyboard preview the corresponding pad lights up. (If i play a sequence or push a note in the midi controller the Pocket piano does not receive anything apparently).
I am using the Oxi USB C to A cable.
This would indicate that the 201’s USB-A port is working, right?
It might be a MIDI setting that needs to be changed. Please see the 201 Manual section about MIDI Settings, and double check that these two settings are correct on your midi.txt file.
Don’t forget to save your changes! And then reload the mother patch by holding the high E + F + G keys and then press Shift.
