I’ve been using a pedal on my FCB1010 to control the speed (ie pitch) of the loop, but it requires attention to the speed to create a smooth effect (of course, I love erratic shifts as well!) But lazing in bed I had an idea and bu**er me, it works!
You simply create an (empty) audio clip on the same track as the looper, then open the envelope window for it, select looper / speed then draw in the envelope. Triggering the clip then performs the action. This can be smooth or not, as you wish – you can even have it jump up and down by fixed note gaps. If the loop is a seamless single note, this in effect creates a pitch-shiftable drone.
I’ve set up 1,2 & 3 octave drops/rises and one also fades up reverb length & level (using the same principle) – this gives a slow drop of 3 octaves as the reverb effect deepens. I also set a “looper off” signal to the envelopes so when it’s dropped, it stops & the reverb shimmers on – nicccce.
The envelope technique allows you to preset all kinds of dramatic effects, occurring simultaneously and in far greater depth than using both hands and feet!
I’ve been inspired to make a video tutorial. It’s taken the best part of 4 hours to get it done (and the quality sucks) but hopefully they will become quicker, better and easier to make with practice. I’ve used SMRecorder – advice on better (free) software appreciated!
Guitarist Bill Vencil does a weekly Youtube series about ambient guitar. Here he demonstrates what can be done with long 4 second delays like they were used in Frippertronics. The focus is on musical structures, not so much on technology.
“The cassette tape echo employs the same basic principle as legendary vintage units like the Roland Space Echo or more primitive reel-to-reel tape echo setups, but using much cheaper and more readily-available used cassette technology”
