SLOOP Pro 2.8.3

SLOOP Pro 2.8.3: SLOOP on the M-VAVE SMK-37

Install from the browser: https://isod89.github.io/sloop-pro/ (Chrome or Edge). The keyboard must run M-VAVE's
V016 first; the page picks the package for your model (SMK-37 Pro / Starrykey 37 Play, SMK-37 Elite, MKE-P37).

New in 2.8.3

• SLOOP 2.8.3's fixes. The kick is no longer cut on a busy beat: a drum hit takes a free voice first, and the
  kick last. The hold pages no longer flash on a quick tap. A free take keeps a held note under the notes played over
  it. A chopped sample played again starts from silence with its ATK, so it doesn't click. The second core is hardened:
  a USB backup no longer crashes it, and if core 1 fails, the keyboard goes on with one core.
• SLOOP 2.8.2's fixes. Hold a note under others: on a POLY track, a note you hold keeps sounding while you record
  over it. When you overdub, it goes on through the notes already there. SEQ > NOTES LEN runs on under later notes, so
  you can put a long bass under a melody. A mono sound says MONO: SET VOICE POLY. No note stays stuck when MIDI comes in
  too fast.
• Four sample banks (USR1 to USR4), as on the FM-1. The SMK-37 has 40 KiB a bank. The editor keeps 22 kHz when the
  sounds fit and switches the bank to 11 kHz when they don't, so a bank still holds about 7 s. Samples from 2.8.1 need
  to be sent again.
• Pads triggered like a drum module's. The velocity is taken at the peak of the hit, with a mask after each note,
  a retrigger cancel that follows the pad's decay, and a baseline that follows the pad at rest. A pad hit flashes
  white. The menu has a new PADS section with three items:
  • PAD THRESHOLD: LOW, MID, HIGH, MAX.
  • PAD LIGHTS: the pads' brightness.
  • PAD SCOPE: a trigger monitor. It shows what a pad measures and stops on a double hit, for a photo with your
    report.

Each package refuses another model before anything is erased. The factory calibration is never written. M-VAVE's own
updater (M-UPGRADE) takes the keyboard back to the stock firmware at any time.
