There is a cool way of doing this (gradual phase changes) with a drum machine and a looper. Connect the drum machine to the looper and MIDI sync them together with the drum machine being the master. Record a loop of the drum machine groove and keep the drum machine groove on. Next there are two ways of hearing a gradual phase change: 1) Disconnect the MIDI sync and one of the two machines will inevitable speed up or slow down 2) Disconnect the MIDI and increase or decrease the drum machine tempo by a very small amount (e.g. from 90 to 91 or whatever) Last of all, sit back and listen to the phase changes - hate to admit it but I've done this for hours - automatic minimal music! BTW, this is more or less based on the technique used by Reich on the _It's Gonna Rain_ Talk to ya later, Rob Jeff Duke Sr. wrote: >Hey ya'll, >R&T, or anybody, could you explain what gradual changes in phase means,I am >going to look for Reich.It sounds cool and I have been wanting to do some >looping with real and analog drums. >thanks much,Jeff >R & T Cummings wrote: >> Some interesting ideas with the minimal music approaches, I think. >> One of favorite pieces is Steve Reich's _Drumming_ which at >> 1 1/2 hours length involves "changes of phase position, pitch and >> timbre" (liner notes).
