The bad news is that I've come up with several great but complicated performance improvements to envelopes and especially LFOs that I want to make before I continue work on Turbo Mode. (In essence, turbo mode is so complicated that I want to absolutely finish a module and carve it in stone before further modification.)
I've also long had qualms about the Filter, which was the second or third module I wrote, back when I knew nothing about sound software
. As with LFO and Envelope, I don't want to implement Turbo Mode on the Filter then change the filter later. I need to make whatever change I make NOW, THEN continue Turbo Mode.
