While i agree that tables are pretty nifty.
With all due respect… the tracker does not need it.
A combination of automation and step effects can get you a long way (if you put some arm grease into creating/copying/editing patterns). All it needs is more flexibility in the automation and chance section and there is plenty of wishes for it:
- A:B conditions for each sequencer pass
- Secondary / Enhanced Chance Step FX
- Change Envelope Automation Values via StepFX
- Expand Instrument Automations and Step FX
- Step FX for: Automation LFO Amount
- User-Assignable Instrument Automation Destinations
Go vote on any of them.
