i m about to build a MIDImerger
but i’ve noticed it needs an external power supply, which is not what i planned !!
(i want it to be protable as possible)
is it possible to power it with a battery (say 9v) ??
Yes, you can power if with a battery.
A user tried to power the merger from the MIDI line, it worked very unstable and not with every synth - so, I cannot recomment this.
