KeyStepPro Studio v0.7.0
Two editions from one source tree, both free and open source (AGPL-3.0). Lite is the recommended one: it is the editor, nothing else. Full is the same editor plus VST3 hosting.
Which one do I download?
| Lite (recommended) | Full | |
|---|---|---|
| Edit patterns, drums, scenes, chains, arp, tempo, swing, MIDI channels | yes | yes |
| Read / write the KeyStep over USB, backups, library, generator, MIDI monitor | yes | yes |
| KeyStep clock readout (Play/Stop, position, BPM) | yes | yes |
| VST3 instruments and effects per track, audio output, WAV recording | no | yes |
| Installer | KeyStepProStudio-Setup-0.7.0.exe |
KeyStepProStudio-Full-Setup-0.7.0.exe |
| Portable zip | KeyStepProStudio-0.7.0-portable.zip |
KeyStepProStudio-Full-0.7.0-portable.zip |
| macOS zip | KeyStepProStudio-0.7.0-mac.zip |
KeyStepProStudio-Full-0.7.0-mac.zip |
Both are maintained. The editions replace each other if you install one over the other. Lite does not make sound: play the KeyStep through its own outputs or your DAW.
What changed
- New Lite edition (no VST3 SDK, no plugin helper). CMake option
KSP_ENABLE_VST_HOST(OFF = Lite, ON = Full). - Rec (overdub) removed in both editions: it only recorded the echo of the KeyStep's own sequencer.
- Lite: Seq / Arp / Drum keys are lit correctly when a project loads.
- Library: double click or Enter opens a project, and the window closes after opening.
- New track card chapter in the manual; screenshots refreshed.
- Installer and CI build both editions (Windows and macOS).
Install
Unsigned: SmartScreen will warn ("More info" > "Run anyway"). SHA-256 sums: SHA256SUMS.txt (Lite) and SHA256SUMS-Full.txt. Close MIDI Control Center before connecting. Only official firmware 2.5.20 is written to, with a backup before each write and a read-back check.
macOS: KeyStepProStudio-0.7.0-mac.zip (Lite) and KeyStepProStudio-Full-0.7.0-mac.zip (Full), universal (Apple silicon and Intel), macOS 11+. Ad-hoc signed, not notarized: the first time, macOS says "Apple could not verify": click Done, then System Settings > Privacy & Security > Open Anyway (details in the manual, chapter 1). Each zip has a .sha256 file.
