I'm planning to make a new SCC Tracker which has features that are already done in previous trackers like SCC-MUSIXX, SCC-Blaffer 1.0 and SCC-Blaffer NT and some features more... I'll list them below hoping to get response and ideas for other features:

• Full Sound Cartridge Support (5th wave, built-in memory for replayer)
  
• Full PSG Control (Two-way, Note/Volume <-> Percussion through kinda BNT-PIE)
  
• More Events Per Step (IT-style editor, multiple events per step <-> MB-type entry)
  
• Integrated Editor (SCREEN6)
  
• Real-time Wave Conversion ('Fade-over' from one to another wave)
  
• Improved key-detection
  
• At least Philips Keyboard support
  
• (Real-time recording from keyboard?)
  
• Chip Selector (SCC/Sound Cartridge, PSG, Both, maybe even 2 SCC's at the same time)
  
• Position/Pattern Usage
  
• DOS2 support
  

More feature wishes are welcome.

Seriously, ANOTHER SCC tracker? ^^;;;

Well, there are some things the other trackers still don't have. One of which is Sound Cartridge support, meaning 5 different channels and PSG support is far from complete in existing trackers IMHO.

A feature that should be interesting is the conversion of SCC/PSG sounds to FM sounds.
I got this idea by testing the X68000 emulators and by playing in these emulators the conversion of the Nemesis 2 MSX game ! The result is beautiful and you can still recognize the original SCC sounds !

That would require quite some in-depth knowledge of the FM sound structure and since I'm not that far yet, some help is very much appreciated.
