Is there a anything out there now that does what Optomadic Midi File Stripper did?

[Moe Shinola]

I really need to strip the program change data from a bunch of midi files. Any input would be appreciated.

Well, after I showed the Event List in XT and deleted the Program Change event, problem went away. Too bad I have to do it one loop at a time.Is there a way to do it as a Batch process?

I'd like to bump this thread, so frustrating to have this on the web, but fileden not hosting the file any more. I've a lot of my midi files that have program changes I need to remove. Hunted high and low for this software or similar, batch processing a must.

There should be a way to filter them in your host that plays the midi files. If not change your host… Maybe Piz Midi has a VST that does that…

Thanks, there probably is, but it'd have to process batches. I'll check on Plz midi thanks for the suggestion.

could you send me two midi file, one with the PC to strip and the other one without it ?
I will try to script what you need with Python
Are you on Windows or Mac ?

[bookofthoth]

Hey so sorry, I didn't get a notification for this.. I'm using windows (10) will I need to install python?

The software would need to strip out program changes.. as in this link
https://www.recordingblogs.com/wiki/mid ... ge-message

and any volume or pan changes which would be CC7 and CC10 respectively.

install python3
type in a terminal : python3 -m pip install mido
move your midi files to a test folder
copy the code below into a file text called strip_midi.py
move the script inside the test folder and execute it :
python3 strip_midi.py

Code: Select all

import mido, os

root_dir = "."

for subdir, dirs, files in os.walk(root_dir):	
	for file in files:
		#print(file)
		if file.endswith(".mid"):
			file_path = os.path.join(subdir, file)
			# Load the MIDI file
			mid = mido.MidiFile(file_path)
			print(file_path)
			# Create a new MIDI file with the same type and ticks per beat
			out = mido.MidiFile(type=mid.type, ticks_per_beat=mid.ticks_per_beat)

			# Iterate over all tracks in the input file
			for track in mid.tracks:
				# Create a new track for the output file
				out_track = mido.MidiTrack()

				# Iterate over all messages in the track
				for msg in track:
					# Check if the message is a control change message with control number 7 or 10, or a program change message
					if msg.type == 'control_change' and msg.control in [7, 10] or msg.type == 'program_change':
						# Skip this message
						#print("CC ou PC trouvé")
						continue

					# Add the message to the output track
					out_track.append(msg)

				# Add the output track to the output file
				out.tracks.append(out_track)

			# Save the output file
			new_file = file_path.replace(".mid", "_new.mid")
			out.save(new_file)

Sorry again for late reply, thank you so much !

I'll be trying this later.
