So its a mellow day's night again, and I'm sitting down to try to find a tuning formula for the Renoise 3.1.1 Lofi Mat device, so I could abuse it in one or another interesting way.
I found the Lofi Mat has broken tuning. Tuning its rates to match certain frequencies - it will display a different frequency than its decimator is actually working at. This could be circumvented, but even worse, the tuning seems also to be slightly dependent on the master sample rate, so tunings to match a frequency I found at 48khz are no longer valid at other rates.
Can this be fixed? I just made a nice instrument using the chorus decimator, having it tuned keytracked. Sounds very digital. Would have liked to use the lofimat though, much grittier sound and extra noise.
