Sampler track is a great concept, but modestly executed.
Groove Agent 4 SE does all that sampler track does and much more (maybe except portamento).
Issues and shortcomings of the Sampler Track:
- there is mono mode, but there no legato mode with audiowarp inactive
- filter has no key tracking
- no lfo’s - there should be at least one for Filter, Pitch and AMP - with delay parameter and velocity sensitivity
- envelopes are loopable, why aren’t they syncable?
- no midi control
If the lacking features were added, sampler track would stay simple but would become a truly inspiring musical tool.
