Controls

In the order the definition gives them, by group. Under each control is the name a program calls it by, once pymidiinstrumentdefs.load("waldorf/streichfett") has loaded them.

Where these facts come from

Source documents

streichfett_manual_v1, version 1.2 (2020), its user manual, read on 13 September 2026 (the file read).
Streichfett EN – Waldorf Music, its product page, read on 14 September 2026.

How they were read

Reference manual, 31 pages: the MIDI Controller Numbers table at p. 21, which gives a value range for every controller; the MIDI Implementation at p. 22; MIDI channel setting, and the second channel the Solo section can be played on, at p. 18; the technical data and factory settings at p. 20; and what Balance does at p. 14, with its sound parameter at p. 26. Polyphony, which the manual does not state, is from Waldorf's hardware product page as saved on 2026-09-14, which gives each section its own, and so is the firmware, 1.14, the only one that page offers. One fact is measured rather than read, and says so where it is used: that the Solo section's channel takes notes but not control changes, measured on one unit running OS 1.14.

NOT RECORDED: aftertouch and clock, which neither source covers.
