by ORL

Hi! We just released a brand bu clip available on PeerTube: Plagiat - J'ai acheté·r un Agno Gastrik chez Wish & Lidl https://videos.domainepublic.net/videos/watch/69e6cee3-c3a9-4090-ad88-43a31… 13'34" of rap-in-opposition, amateur-mainstream-rap, zeuhl-rap, experimental-rap, zappa-rap, thing-fish-rap or watchamacallit! It's been fully-realized with FOSS only (audio and video), mainly ardour, kdenlive, but also Jamulus for the last part which is a gig between two bands away from 500km.

Actually a Korg M1 data dump question: Decoding files that begin "00 10 00 3C"

by Kevin Cole

Hi, I've gotten it into my head to try to try to decode some files from 30 years ago and see if I can extract enough MIDI -- and perhaps, instrument modifications -- to be able to approximately recreate the audio on Linux. The files were created from a program I wrote and have long since forgotten. Using the old Korg M1 manual, helpfully scanned in by Korg, I've been able to determine that most of the files start with the "exclusive header" and can be categorized as to which type of dump they are. From there, I should be able to break apart the data. However, I have a several files with the extension ".sng", which would suggest "song", but the opening bytes are not the "exclusive header" but rather, in hex are: "00 10 00 3C" followed by a list of 16-byte ASCII strings containing instrument names (followed, for a while by mostly 00000000 and/or FFFFFFFF before getting to something a bit more variable) Skimming through I also eventually see what appears to be a "song title" in ASCII. Is anyone familiar with what type of beasties these files are, and is there a good spec for the format? Thanks. P.S. (I only had access to the M1's for one semester, and the code was written on the school's Atari ST-1040, which I'd never seen before nor have I used one since.)

[music] From the starlight (dark synth imrpo/soundtrack)

by Jeanette C.

Hey hey, something a little Vangelis SciFi soundtrack for a change: https://youtu.be/ul570vi8W58 and for direct OGG download https://www.dropbox.com/s/lehah6hzyqlhqda/from_the_starlight.ogg On Linux I used Yoshimi for the big pad bass and Hexter for the high bell. As this is a "sound per synth" setup, which could have been recorded live, once the sequences were going, I used all my very synthetic hardware: Behringer Neutron for bass, RD-8 for drums, Arturia MiniBrute 2 and Make Noise 0-Coast for arpeggios, Waldoorf Microwave XT for the pad and DSI/Sequential Prophet-12 for the lead. In the production there was just some EQ and compression to tame the sounds and a healthy dose of reverb for the atmosphere. I think I ended up using g2verb, since Ecasound and zita-reverb don't always get along.

Fluidsynth: disconnect vibrato from aftertouch/disable aftertouch

by Jeanette C.

Hey hey, is there a way to stop fluidsynth from applying vibrato, once aftertouch is used? I'd be happy to bypass aftertouch all together. I have tried with the built-in router, but got no result.

Have you upgraded or downgraded jack_capture and/or libsndfile since then? Which version of jack_capture are you currently using? Have you tried a different format than wavex? (wav is probably the the safest format to try since it's one that has been the most tested. Wav files has a 2gb limitation though, but jack_capture automatically writes to a new file whenever it reaches that limit.) There was a problem many years ago that I used (by accident) a 32 bit integer instead of 64 bit integer. Perhaps you are using one of those quite old versions of jack_capture.

Long-running jack_capture multi-track recording corruption?

by Andrew Grathwohl

Hi list, I am using jack_capture to record 2 inputs and 20 outputs going through SuperCollider for a duration of between 30-45 minutes, using the following command line: jack_capture -f wavex -p supernova:* test.wav This has worked well for my use case for several years. However, since yesterday this command line fails to capture the entire recorded performance, despite jack_capture showing the meters responding to the audio correctly. Whenever the recording duration exceeds approximately 20 minutes, the output file will only contain the first 5-10 minutes. However, if we only do a 5-10 minute recording, the entire recording is captured and saved properly. Seeking any insights about how to diagnose/fix these problems. Anyone here know where I ought to start? Thanks much, Andrew

Four free SFZ sample libraries

by Jeanette C.

Hey hey, I have just uploaded four sample libraries that I created with AutoSampler and DrumSampler: http://juliencoder.de/sound/index.html They are: Prophet Guitar: a guitar/clav like patch on the hybrid analogue/digital DSI/Sequential Prophet 12 (part of my Jeanny's Genius soundsets). Brute Bass: a solid bass patch on the analogue semi-modular Arturia MiniBrute 2s. Coast Bass: a gnarly, woddy "plucked" bass patch on the west/east coast semi-modular Make Noise 0-Coast. RD8 Kit 1: one drum kit (no congas) on the analogue Behringer RD-8 (Roaldn TR-808 clone), solid, but conservative, so no overlong boomy kick :) ). Hope someone can have some fun with them. Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c It's not complicated We just syncopated We can read each others' minds <3 (Britney Spears)

AutoSampler version 3: two new samplers

by Jeanette C.

Hey hey, AutoSampler version 3.0 is here (and will probably be the last, except for possible bugfixes): http://juliencoder.de/sound/autosampler-3.0.zip (Tested with Csound 6.15, might run with 6.14). There is one autosampler which can pause after a specified number of notes, so you can retune your old analogue synth. You can interactively choose a reference note, byt playing notes on a connected keyboard. A reference tone will be played from within the program. The next sampler is really new: Drum Sampler is specially designed to work with drum machines. It starts in play/exploration mode, where you can tweak sounds and listen. Then in record mode all played notes/sounds/trigger-buttons will be recorded. You can specify MIDI notes for hihats, they will be put into a mute group for the SFZ. SFZ files are created at the end. Round robins will automatically be detected. Play a note as often as you like. Files are named based on the MIDI note. You can simply rename them. I have recorded a sample set with each sampler, if anyone's interested, I can upload them. Good sampling and best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Baby, take the time to realize I'm not the kind to sacrifice <3 (Britney Spears)

Released a small auto sampler

by Jeanette C.

Hey hey, I have released a small autosampler, implemented in Csound. It's easy enough to set up. http://juliencoder.de/sound/autosampler.csd Documentation for non-Csound users is at the top and again at the bottom. The autosampler support velocity layers, round robins, overall note range, note intervals, both mono and stereo sampling. The sampler will wait for a note to decay, but does not (yet) produce key release samples. Output files are named: chosen_name-MIDI_note_number-velcity-round_robin_index.wav I hope someone finds a use for it. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c All I need is time A moment that is mine While I'm in between <3 (Britney Spears)
