new wave on each key press

[Sleepwalker]

Hello!

Im trying to make an effect that im using on my monomachine synth which I do this way:

I select a wavetable osc, and select the wave ecsactly in the middle. I set the lfo to trigger mode, and the shape to random. This way, each time you hit a key, a new wave will sound and hold, until next time you press a key. (This is very cool!)

Can this effect be applied to the Ti? Im not shure how to set the lfo to work like this. Maybe by using its envelope mode as trigger? But where is the random waveform?

Sample and hold, and S&D, but whats that?
