Rotary Speed Decimal to RPM Conversion

[taylorbeats]

Slow speed and fast speed are decimal numbers in the Helix, is it safe to say that 1.0 equals 100 RPM?, 2.0 equals 200 RPM?  Would seem logical.

I would assume that 1.0 = 1.0hz ie 1 revolution a second

you kow what they say about assumptions... Measure it maybe?

Seeing that it is not labeled with any unit of measure, it could be that it's because the speed parameter for this effect is reactive with other parameters, making any unit indication a bit senseless. I've noticed that there are a few modulated effects where a parameter seems like it should be labeled but isn't. So there must be a reason some parameters (I think all of them are time based) are not labeled.

The Leslie speakers I remember from a couple of bands I was in didn't have speed adjustment other than fast or slow. I'd say adjust to what sounds good to you. Maybe listening to some classic examples would help you. I always loved the sound of it winding up and down....

I took the vibe rotary and loaded it in reaper to get an idea of the pulse timing.  I set the metronome to 370 bpm, recorded a bit of some single notes.  Seems that the setting corresponds to 100 rpm multipliers. 1=100 RPM, 2=200 rpm etc..  The original had a slow speed and fast, and the slow speed was about 40 rpm, fast about 370 rpm.  The 3.7 setting seems about dead on to the 370 bpm metronome. That setting with the roto-vibe dropped into a parallel path post amp, pre speaker sounds perfect for what I was shooting for.

For the record, you can actually sync the slow and fast speeds for the rotary effects to the patch BPM and have them tied to the tempo you tap in. Just hit the knob under the slow or fast speed parameter to change that value to a note value. Or in the editor, just click the button to turn tempo sync on on the effect's home screen.
