Wavetables and stepmodulator

In Halion 7, on a macbook pro, am trying to use the stepmodulator to modulate the position on a wavetable without success. The mod matrix won’t allow that to happen. It won’t even allow an LFO to do this. There’s probably a simple fix to this, but I can’t figure it out. I’ve dredged through the manual without getting enlightened.

Thanks in advance for your help!

Have you turned up the Amount on the Modulator sub-window?

Hi Peter - Thanks for the suggestion. I tried raising the Amount on both the Stepmodulator and on the mod matrix destination slider bar. Nothing is happening. It seems like there’s some on/off divide between the wavetable I’ve loaded up and the modulation matrix destination for wavetable1: position. I can use the mod matrix to set up panning, levels, pitch, but no further than these top-of-the drop-down list choices.
