Hi everybody. I'm approaching to the Behringer FBC 1010 midi foot controller and I would like to use it with both Rakarrack and Sooperlooper simultaneously. The problem is that Rakarrack is supposed to automatically assign a preset to every MIDI signal received, so everytime I send a message that I would like to address to SL only, RK reads it too, changing preset when I would like it did not. I'm scanning the source code and trying to use FLUID to edit it, looking for a section where I can see and delete the MIDI signals that I'd rather use with Sooperlooper only. Unfortunately I'm not a programmer and nothing looks familiar to me with FLUID. Does anybody have any useful information about MIDI and FLTK or C++? Is it possible to delete sigle MIDI values in the source code? Thanks in advance. Andrea

[New music] soundtrack: Observation P

by Jeanette C.

Hey hey, just wanted to post it, less than 30 seconds, done for a competition: https://soundcloud.com/jeanette_c/observation-p-adamaudio-soundtrack-2018 I am trying to continue the soundtrack. The melody was a happy accident, but it has carried some momentum for me. Enough so that I am currently recording a sort of "main title" at least. Hope you enjoy it!

Creating an impulse response from sine sweep in the terminal

by Jeanette C.

Hey hey, can anyone think of a method to create an impulse response from a sine sweep using the commandline only? I can work with a predefined sine sweep or create a sweep due to a certain formula. I can make sure that it starts as soon as the recording starts. Not sure what else might make the task easier. I know that there is Aliki, but sadly it's graphics only, and IIRC Fons has written has own little widget library, which isn't even accessible with Orca. Any ideas?

setBfree: not accept ALSA MIDI driver

by Jeanette C.

Hey hey, I've tried to configure setBfree to use the ALSA MIDI sequencer API for MIDI ports, but to no avail. The relevant line in my configuration reads: midi.driver=alsa There is no error message on the console and I specifically included the config file using the -c option. Can anyone help to settle this, please?

LAM

by Will Godfrey

Linux Audio Music has been dormant for a very long time, but recently I contacted the the person who hosted and ran it. The reason he closed it was because of a serious vulnerability was discovered in Rails, and he no longer had time to do the necessary upgrades. However, he has told me that he still has the entire database and the code. In his own words: "... would be happy to host and do what I can to facilitate a handoff to someone else who wants to manage it." For anyone who doesn't know, this was a relatively simple and clean site aimed specifically at providing a home for tracks composed with Linux - something rather rare! -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

jack-dssi-host: chooose plugin UI

by Jeanette C.

Hey hey, is there a way to choose a plugin's UI using jack-dssi-host from the terminal? I'm thinking of hexter, which has a gtk and a text UI, but I haven't been able to choose the text UI, since it's listed as the second one.

OT: SSD disk prices have dropped?

by Ivan K

I need to replace a hard drive that recently went bad, and the new drive needs to be at least 1TB. I was looking on Amazon and debating whether to buy a 5400rpm versus 7200rpm disk, when, just for fun, I thought I would price 1TB SSD disks. I started finding things such as this: https://www.amazon.com/Inland-Professional-Internal-Solid-State/dp/B07FM9SS… Inland Professional 1TB SSD 3D NAND SATA III 6Gb/s 2.5" 7mm Internal Solid State Drive (1T) $140 (USD) https://www.amazon.com/Samsung-Inch-Internal-MZ-76E1T0B-AM/dp/B078DPCY3T/re… Samsung 860 EVO 1TB 2.5 Inch SATA III Internal SSD (MZ-76E1T0B/AM) $148 (USD) Can I just plug one of these drivex into a SATA plug on my motherboard and it will function just like a regular spinning hard disk drive? If 1TB SSD drives have become so cheap, I don't understand why anyone would buy a hard drive that spins anymore, but maybe I am missing something. Am I missing anything?

samplerate conversion targetting number of samples

by Brent Busby

Anyone know some Linux CLI tools that would be good to batch convert a folder of 24/96 samples, mostly small waveform clips about two to four wavecycles long each, down to 8-bit...<drumroll>...and the nearest number of samples that's a multiple of 256 by stretching/squeezing, not by truncation (so as not to ruin looping)? You can see why I don't want to do this to a large number of files with a mouse in Audacity... :) Though if you did do it in Audicity, you can achieve what I'm trying to do by selecting the whole clip, selecting Effect -> Change Speed from pulldowns, plugging in a new length that's a multiple of 256 under New Length (with unit set to samples), and exporting the new file. Except, I really don't want to do that hundreds of times myself, so a scriptable CLI method would be better. Basically, I have some Multimoog waveforms that I've sampled with a good interface, but I'd like to bring them into an Ensoniq Mirage (8-bit), which likes everything to be on 256-sample page boundaries. I'm hoping to do some interesting hybrid/wavetable synthesis if I can get the waves into the machine. The target samplerate is unimportant, because the Mirage is going to adjust it up and down itself anyway because of the way its playback works. Only the length of the clips is important, which should be a multiple of 256 samples, and it can be downconverted by any amount that will achieve the length. Most samplerate conversion seems to target a desired frequency, but I'm targetting the number of samples, and I'm flexible on whatever frequency/resolution conversion is needed. -- - Brent Busby + =============================================== + "The introduction of a new kind of music must -- Studio -- + be shunned as imperiling the whole state, for -- Amadeus/ -- + styles of music are never disturbed without -- Keycorner -- + without affecting the most important political -- Recording -- + institutions." --Plato, "Republic" ----------------+ ===============================================
