Does anyone know of software that can generate MIDI messages from a touchpad? The idea would be to send CCs to a sequencer or soft synth, but being able to send it to an external hardware device would also be very useful. -- Will J Godfrey https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune.

[LAU] Steinway_IMIS2.2 soundfont (no loops fix)

by Roberto Gordo Saez

This is Steinway_IMIS soundfont, version 2.2. ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2 This version fixes the issue with loops. I hope this is the good one and there are no more remaining major bugs. Marcos is a little busy right now, so he asked me to make this fix. He is thinking to make other improvements, so expect more updates soon.

[LAU] [music] Schwinge mein Hertz, du süßer Ton

by Christopher Arndt

I was feeling rather pious this past weekend, so I put the rainbow strap on my keytar and wrote this little hymn to celebrate the resonating universe and the holy FM synthesis. Soundcloud: https://soundcloud.com/spotlightkid/schwinge-mein-hertz-du-suesser-ton Ogg Vorbis download: https://0x20.eu/nc/s/gPeSmBzwxZeGpS6 MP3 download: https://0x20.eu/nc/s/m3kG86An5NNG46a Composed and produced by Christopher Arndt in February 2023. Recorded in Ardour 7 on Linux with a Yamaha Reface DX FM synthesizer and a Kurzweil PC3K into a MIDAS MR18 digital mixer and audio interface. All sounds from the Reface DX, except bass drum and snares from PC3K. Sounds used: "Flute DX" and "Organ Slow" by Tom Ansink [1] , "RetroChoir" (modified) by Jeremy Mulders [2], "Dulciclone" and "Celesta C2" by me, "Basic Orch Perc" from PC3K factory presets. Effects added in the DAW: reverb from "LSP Impulse Reverb Stereo" and Samplicity M7 "North Church" impulse response and from "DFZitaRev1" [3] plugin, multi-band EQ and compression on master bus using "ZamAudio ZaMultiCompX2", and "Calf Saturator". Inspired by a video from Alex Ball: "Dulcitone 1900 | Blessed are the music makers" [4] Share & Enjoy!

[LAU] Software for scanning sheet music

by Bengt Gördén

Hi, I have some sheet music from an old relative of my wife. They are nicely printed on paper (printing shop) and 105 years old this year. I would like to scan them and hopefully have them converted to lilypond or xml or whatever is used today. It seems that MusicXML is the most used today but the best would be lilypond. Anyone know of such software for Linux? I saw an app for iPhone and Android that seemed promising but much cooler would be a native Linux program. Best, -- /bengan

[LAU] SoundTracker 1.0.4-pre1 released

by Yury Alyaev

Hi all, I just have released SoundTracker v1.0.4-pre1. I've decided to make a feature-freeze at this point, this means that 1.0.4 will have no new features comparing to this pre-release, only fixes and small improvements if something will be found inconvenient. So I ask everyone who has interest in SoundTracker to test this release. Here are main features of the 1.0.4-pre1 release comparing to 1.0.3: * General: - Full-screen mode - Volume of all samples of an instrument / all samples in the module can be set to a value, not only gained. Also all samples panning can be adjusted. These functions can also modify the explicitly given values of volume / panning of notes in patterns - Improved compatibility with FastTracker, also MOD files are played more correctly - Unused patterns are listed in the Pattern Sequence Editor - Sampling rate can be specified while saving a sample as WAV - New module optimizer with many control parameters * Track Editor: - Moving notes up / down is implemented * Sample Editor: - External programs can be used for samples processing. The interaction between such a program is described using XML spec, no ST recompiling required - The whole sample is drawn after recording - Exponential / reverse exponential volume fade transients * Instrument Editor: - Envelope inversion and shifting is implemented SoundTracker download page: https://sourceforge.net/projects/soundtracker/files/ Regards, Yury.

[LAU] How to analyse and "optimise" a frequency spectrum? (digitising tapes)

by Jeanette C.

Hey hey, I have digitised a few last tapes. The sound isn't too bad, but all tapes appear to be a little too bass heavy. Since I only work in the terminal I approach the issue with Csound that provides a lot of tools. All kinds of filters, rms/peak metres, an lufs metre and more. First: did I miss an obvious commandline tool that would produce a reasonable solution for that? There are two main issues that I try to improve halfway automatically. 1. Sometimes the stereo balance is a little wrong with one channel being slightly louder than the other. 2. Imrpoving the frequency spectrum, flattening it a little bit. For 1. I have started by taking the file's peak of both channels seperately and simply multiplying them so the peaks match. Over a whole tape side this should be approximately the same. Or should I go with a different measurement? lufs integrated loudness, momentary or short term maximums? For the second issue, I am unsure. I have split the audio into frequency bands using octaves, more or less. So the first band goes up to 100Hz, the next to 200, then 400, 800 and so on. I have used Csound's tone and atone filters: atone highpass filter: https://csound.com/manual/atone.html and the matching tone lowpass filter: https://csound.com/manual/tone.html Then on each band for each channel I run the lufs metre, storing the maximum momentary and short term values and the integrated loudness. Though I wonder: are the frequency ranges and type of filter reasonable? If so how would I approximate a reasonably flat spectrum? Which values to compare to what? I mean: what kind of measurement to use and should I compare adjecent bands and extrapolate fitting values from that or compare one frequency band's measurement to the same measurement on the unprocessed full-band audio? Any hints and practical suggestions are very welcome. Thank you 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 I'm reaching out to you To find that you're not there <3 (Britney Spears)
