No captures in the folder

Using Zynthian

Hi @ll,

i have a problem with recording. When my Circuit Tracks or another novation instrument is connected, the record of audio and midi doesn’t work. Can i set the capture path that it is not switching to a connected USB Device. I run Zynthian on a Pi4 with an external SSD so the normal capture path has enough diskspace and writespeed.

Welcome @micha82!

I wonder if the Circuit Tracks is acting as a mass storage device but not permitting writes?

Yes it acts as a Mass Storage device. I have also other Instruments connected, thats why i asked to adjust the path in a config. Would it help if i add a Partition of the SSD via fstab and this is taken as captures path?

So i git it to work. I added a line in /etc/fstab, so the Circuit Tracks is not mounted

UUID=XXXX-XXXX     None vfat  nofail

Now the captures are inplace.

It would probably be a good idea to add a feature request so that we can handle this more gracefully in the main zynthian code.

we could exclude from mass storage any MIDI device, or ignore read-only units

Better not ignore read only units, because one could use a hardware write protected stick with valuable data. Write protection prevents the data from being shredded by faulty software, so that is why people use this kind of storage media.

We could have a configuration that allows users to flag devices to ignore or a curated list of known offenders… but maybe you want to access the audio on your Circuit Tracks - or whatever.

We could disable saving to read-only media but still allow reading from it.

I mean ignore in regards of using as capture destiny :wink:

This would be the easier approach.

I just pushed a quick fix for this in Vangelis. Only for audio capture yet. If it works i will implement for midi captures too.

Please, update and test.

Wow great! Thx alot, this is very helpful for users. Because i had no idea how to solve the problem because it just didn’t work. I am a bit experienced in looking in the systemlogs so i got a hint with the ro permissions.

Thx for the fix @jofemodo. It works. I remove the fstab entry and made the update, YES :hugs: :musical_notes: :metal:

OK! Now it’s implemented for audio and MIDI captures.

Thanks,
