Status
The status tables below lists the current status on the different parts of the project as of the latest release.
✔️ Implementation more or less complete
❎ Partially implemented, important features still missing
❌ Not implemented
| Feature | Status |
|---|---|
| Decoding PCM ROMs | ✔️ |
| Instrument definitions | ❎ See status table (ADD REF) |
| Reading and decoding PCM samples | ✔️ |
| Resampling / pitch corrections | ✔️ (NN, linear and cubic) |
| Pitch envelope | ✔️ |
| Filter envelope (TVF) | ❎ Initial implementation in place, but lacks full understanding of partial definition for filter envelopes |
| Volume envelope (TVA) | ❎ Mostly done, is missing key follow time adjustments and some velocity sensitivity parameters |
| MIDI CC messages | ❎ Mostly implemented, missing AfterTouch++ |
| MIDI SysEx messages | ❎ All SysEx related to setting internal states are supported, but are missing LCD display messages and all send requests |
| LFO 1 / 2 generation | ✔️ LFO1 and LFO2 definitions are mostly known and implemented |
| Tremolo | ✔️ |
| Vibrato | ✔️ |
| Static filtering (inst. without TVF) | ❎ Code exists, but filter configuration based on ROM definitions needs refinement |
| Chrous (system effect) | ❎ Basic implementation in place, needs refinement |
| Reverb (system effect) | ❎ Basic implementation in place, needs refinement |
| Modulation controllers | ❎ Mostly OK, pitch wheel (the only 2 byte controller) needs improvement |
| Drumset configurtation | ✔️ |
| LCD animations | ✔️ Only found in SC-55mkII ROM |
| Feature | Status |
|---|---|
| Audio output | See audio table |
| MIDI input | See MIDI table |
| Audio device selection | ❎ Needs refinements for ALSA (device list) and macOS (select other than primary device) |
| MIDI device selection | ❎ Done for Linux (ALSA), but work needed for macOS and Windows |
| LCD display | ❎ missing 'Peak Hold' type 3 |
| ROM setup | ❎ missing SHA256 definitions for several known ROM sets (SHA256 -> libEmuSC?) |
| Setting volume | ❎ Volume is in %, not decibel |
| Button interface | ❎ Bug remains: ALL + mute not implemented |
