by Rui Nuno Capela

Hi again! The 'Vee One Suite' of 'old-school' software instruments, * synthv1 [1] as a polyphonic subtractive synthesizer; * samplv1 [2] a polyphonic sampler synthesizer; * drumkv1 [3] as yet another drum-kit sampler; * padthv1 [4] a polyphonic additive synthesizer. Are also being now released as the second batch of the so called 'QStuff*' (northern) Winter'22 season. Change-log: - Dropped autotools (autoconf, automake, etc.) build system. - Fixed deprecate warnings in preparation for Qt >= 6.2. All delivered in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.24 (winter'22) is released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

RtMidi peak at messages or determine if a message is pending

by Jeanette C.

Hey hey, is there any way of finding out whether a big SysEx message is incoming, before the normal callback is invokved or I suppose one of the buffers is full? May it be viable reducing the buffersize (version 5.0.0) and increasing the number of buffers? The manual for this function mentions that this will not change anything on most APIs, since they handle buffers internally. Many thanks for any pointers!

Re: [LAD] Quantise MIDI note/frequency to musical scale: algorithm?

by Jeanette C.

Thanks Roman. For the actual pitch quantisation I used a similar approach in the end. Though for the MIDI case I stuck with the temporary 128 element array. Though this is simply calculated from the same set of 12 element arrays.

This provides immediate feedback, so people will actually learn the set of allowed notes, and I guess that will happen quite fast. If instead you replace the unwanted ones, the user will learn either nothing, or the wrong things, e.g. that C# is a valid note in a C-major scale. > Initial thoughts on the MIDI note case included creating a 127 element > array and fill it with notes only in the scale and then use it as a > lookup table.

There is code doing this in zita-at1 (the autotuner). It has some refinements such as an optional preference for the previous note. I will look this up and isolate it - it may be difficult to find as it is integrated with other functionality. Ciao, -- FA

python-alsa-midi – new Python interface to ALSA sequencer

by Jacek Konieczny

Hi, When working on my hobby project, a Raspberr-Pi based wireless foot switch for my VOX Adio Air GT guitar amplifier, I hit, once again, the same problem: there is not good Python library for use with ALSA MIDI sequencer. Those that can be found on PyPI are either very outdated an unmaintained, useless with modern Python 3.x, or they use one of the portable MIDI libraries (PortMidi or RtMidi) and lack much of the ALSA sequencer API functionality – useless for my use case, where the MIDI port may appear and disappear at any time. Last time, with another project, I wrote my own limited bindings. This time I had no urge to code any C any more. I decided to use cffi this time and, instead of making limited set of bindings for the one use case, to make a proper Python package. And here it is: https://github.com/Jajcus/python-alsa-midi/ https://python-alsa-midi.readthedocs.io/ https://pypi.org/project/alsa-midi/ The project should work on any Linux distribution and architecture (provided ALSA kernel module and library is available), on Python 3.7 to 3.10. Asynchronous asyncio API is also provided. The API is not complete yet – some ALSA sequencer API functions are not covered or not fully covered, but I think it is complete-enough for most use cases. I am thinking about adding raw MIDI API too, just for the completeness, so the package name is not confusing. Now it is great time to evaluate the new API, as I would like to make a 1.0.0 release soon and then I would rather not do any backward-incompatible changes. I hope someone will find this code useful. Greets, Jacek

Quantise MIDI note/frequency to musical scale: algorithm?

by Jeanette C.

Hey hey, I'm currently working on something and need note/pitch quantisation to predefined musical scales. Some research has almost entirely yielded such features in DAWs and hardware modules that can do it. Is there a type of algorithm typical method to achieve that in realtime? I'm not averse to using lookup tables over the full MIDI range or possibly an expected pitch range. Any help or pointers are welcome. Many thanks 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 believe We all have one true love Somewhere in this world <3 (Britney Spears)
