Compared to the ST editors.
- K4 is a universal editor, ST has editors for each instrument.
- K4 has editors for Velocity, Pressure and Intonation map and more to come.
- K4 already fixes quite some bugs and omissions in ST :
- Tuning map, category and subcategory selection.
- Trigger setting list is complete.
- Coarse pitch change does not affect Timbre shift and Transpose.
- Full range on filter width.
- Fine Hz / Tune properly named i.s.o. "Output".
- Proper names and correct ranges in DSP function blocks.
- Osc Key Sync.
- Real-time control of Pad.
- KB3 Pitch is updated properly.
- KB3 Key Click Key and Key Track implemented.
Why another editor ?
- It all started some 30 years ago with the K2000 and some mailing list members
(including Brian and Jason IIRC) who tried to decipher its sysex implementation. - Then some time ago I had a Sequential Rev2 with an ST editor.
There were some Edisyn editors for the Prophet 08, Mopho and Tetra,
so I got in contact with Sean Luke, who developed Edisyn, and I made an Edisyn editor for the Rev2. - I also had a full-option K2600 76-key without an editor so I tried to make an Edisyn editor for it.
I eventually gave up on that, but lots of ideas of that project went into this K4 editor. - The K2700 arrived and I wanted to decipher its sysex protocol.
People like Jason, Brian and Mike had already done a tremendous job on the PC3.
Based on that work, I developed a receiver/parser/dumper in Edisyn, also using the experience with the K2600.
Then Jason suggested to try Juce as a development platform, and this was the birth of the K4 editor.
