Performance modulation sources each route to up to four parameter destinations with independent depth

The Digitakt II exposes several performance modulation sources — KEY TRACKING (played/incoming note pitch), VELOCITY MOD (note velocity), AFTERTOUCH, PITCH BEND, and MODULATION WHEEL — each configured in the SETUP menu > TRACK. Every source uses the same routing mechanism: assign up to four PARAMETER-page destinations, each with an independently set, bipolar depth (offset from the parameter’s base value). Key tracking is the standard mechanism for filter tracking (opening the filter at higher pitches) — without it, sampled notes sound darker high and brighter low. Velocity Mod enables dynamics: harder playing can raise filter cutoff, overdrive, or reverb send. Sources combine — a loud, high note could simultaneously open the filter more AND increase reverb send. The manual defines all sources as behaving the same way as KEY TRACKING, so learning one routing screen transfers to all five.

Examples

Assign KEY TRACKING: destination=FLTR FREQ, depth=+40. Now playing the same sample at C5 opens the filter further than at C2. Assign VELOCITY MOD: destination=AMP VOL, depth=+60 for velocity-sensitive dynamics.

Assessment

You want a sound that gets brighter AND louder with harder playing. Which SETUP-menu source do you use, and what two destinations do you assign? How does its routing differ from KEY TRACKING’s?
