How to change the scale in the tempo knob?

[Petsu]

I’d like to change the tempo knob scale. The slowest tempo is 200 bpm I think, when the tempo knob is turned counterclockwise, but I want it to be a certain tempo to sync it with my delay pedal. Is it possible to change it?

If you want to scale the tempo knob you can change the numbers at the top left of the [pd metronome] sub patch.

The tempo knob (like all the knobs) goes from 0 to 1. Currently it scales this to a BPM from 50 to 250. If you wanted it to start at 1 BPM, change [+ 50] to [+ 1]

You will need to install Pure data on your computer to do this modification. Once installed, please follow the instructions for ‘Disk Mode’ here:

Open up mother.pd and then the [pd metronome] subpatch of mother.pd. Set PD to edit mode and make your change.
