This weekend I was jamming at Nurdspace Wageningen with some new gear + some gear that a friend made.
I used the buztrum to control a rather simple 6 voice karplus strong patch on an Axoloti (may share the patch on request). With plenty of added effects (compression, eq, chorus, and delay) on all the tracks using the mixer.
The LeStrum is a midi controller with 36 chord buttons and a section of capacitive touch 'strings'. The buztrum is an implementation of the device done by buZztiaan.
