Volca FM Buddy will allow you to send DX7 sysex patches to your Volca FM using just a stereo or mono audio cable*.
Loading DX7 sysex patches is easy:
1. Open a DX7 sysex file from Safari, Mail, ...
2. Choose a patch from the collection to send.
3. Connect an standard audio cable to the in jack on your Volca FM and your iPhone.
4. Turn up the volume to max and hit send!
It will only take seconds to transfer to your Volca FM. Once there you can save or discard the patch. Please note that the Volca FM isnt an exact clone of a DX7 so patches may not sound exactly the same. Most of the time minor tweaks will get the patch sounding correct.
More features are in the works, like saving and loading Volca FM patches!
* iPhone 7 will require the dongle since there isnt a headphone jack.
