The following video shows you how to quickly build the circuit on a breadboard so you can try it out. I'll get to work on designing a proper enclosed version.

Pretty Cool, It will work with Wahammy 4? (a lot of double u on a short frase)
ReplyDeleteHi Claudio. I don't have a 4 so I have no way to test. But I would say no.
Deleteit works with Whammy DT, thanks Dave
DeleteThe link for the midi interface is no good, please fix
ReplyDeleteHi Mika. It's fixed.
DeleteThanx Dave.

ReplyDeleteSo will this work as a sequencer for my Whammy 5? If so, how do I program a sequence into the nano? Thanks!
ReplyDeleteSuperb posts with lots of information!!! This is really the most miraculous blog site dude….

Hi Dave!
ReplyDeleteFirst of all, you did a great job on this build. It´s a very well explained and conceived project, so it was easy as pie to follow your instructions and build my own WHAMjammer. I had a lot of fun since! Altough it works just fine in general, lately i had some issues when using the WHAMjammer together with other timebased effects (for e.g Strymon Mobius set on Pulsewave Tremolo). It seems that the sync of one of both effects is oscillating, causing oscillating phaseshifts between the tremolowave and the arpeggiated Whammysignal. Both devices are receiving Midisync and CC form the same Midiport. I´m assuming that the groundingresistor connected to the 6n138´s Pin7 could cause that issue, since it´s affecting the midisignal, right? Otherwise, could it be possible that the arduino nano simply isn´t fast enough, interpreting and converting the incoming midisignal for the whammy to stay in sync? I´m pretty sure, that the Mobius isn´t part of the problem, since it works fine with other gear and also Ableton Live.
Thanks in advance, Mutethatdude
