Tools for handling Phrase Pad data from Casio musical keyboards, especially CT-X keyboards
[WORK IN PROGRESS] Tools to translate between CPFF (Casio Phrase File Format) and Standard MIDI. CPFF is used as the format for Phrase Sets and Phrase Pads on the CT-X range of keyboards.
A file with extension .PHS saved by the CT-X keyboard can be converted to a standard MIDI file by calling (for example):
> python phrase2mid.py PHRSET01.PHS > 01.MID
It also handles phrase sets read directly from the keyboard. The following snippet of Python code will do that (note that the downloading portion of this will only work under Linux. The processing from phrase to MIDI is agnostic to Linux/Windows):
from internal.sysex_comms_internal import download_ac7_internalfrom phrase2mid import process_phrPHR_NUM=4 # 0-3 are Phrase Set 01, 4-7 are Phrase Set 02, ... 96-99 are Phrase Set 25.y = download_ac7_internal(PHR_NUM, category=35, memory=1)with open('MyPhrase.MID', 'wb') as f:process_phr(y).writeFile(f)
Writing MIDI uses the midiutils library (https://pypi.org/project/MIDIUtil), which must be installed before doing phrase-to-MIDI conversions. Reading
MIDI uses home-grown code which doesn’t need anything to be installed.
