Hey hey, I'm experimenting with c++ trying to program something nice for MIDI. I'm now experimenting with clocks, using both the standard c++ chrono library and the boost chrono library. My example program sets a desired delta between ticks of 250ms. I see that there is a difference, since Boost chrono can also use pthread thread parameters foor realtime scheduling and priorities. With the standard chrono and thread library my ticks are usually out by anything between 150.000 to 290.000 nanoseconds. Using boost a tick is out anything between 110.000 to 124.000 nanoseconds. Yes, much better. But, assuming that I correct the drift, does it make a difference for MIDI instruments? I know one of my MIDI instruments with a clock sync'able delay can be rather touchy with MIDI clocks, but are there good estimated guidelines experience values how precise ticks should be? Best wishes and thanks for any help, 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 Top down, on the strip Lookin' in the mirror I'm checkin' out my lipstick <3 (Britney Spears)

Text editor with new views in separate windows (not tabs or split views)

by Will Godfrey

Up till now I used Kwrite, but in recent versions this now only supports split views and tabs, and no longer new views in a new window. Separate windows in my preferred style, and I find I can work much faster and more accurately that way. Does anyone know of a text editor that still does this? I've not been able to identify anything on the usual search engines, nor with Wikipedia :( -- Will J Godfrey {apparently now an 'elderly'} https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

by Rui Nuno Capela

Hello again, Qtractor 0.9.31 (winter'23) is out! Change-log: - Fixed a off-by-one rounding error on MIDI clip offset and lengths that were leaving some clips unlinked on load. - LXVST_PATH environment variable now accrues to VST_PATH for Linux-native VST2 plug-ins search path and not taking over in precedence anymore. - Fixed an old mistake on custom aliased CLAP and VST3 plugin paths. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

[ANN] Qtractor 0.9.30 - An End-of-Year'22 Release batch #3

by Rui Nuno Capela

Hello one third and last time this year, Qtractor 0.9.30 (end-of-year'22) is released! Change-log: - Plugin latency/delay compensation now in effect immediately after changing track option (cf. Track/Properties... /Plugins/Latency compensation). - Shade-off regions not-in-view from the thumb-views. - Improved MIDI queue time drift correction resilience and stability against in-flight tempo changes. - The main real-time process cycle now runs on uniform block-sizes, in strides of 64 frames per period, meaning a higher resolution automation, independent of buffer-size. - The internal main MIDI engine gets its ALSA sequencer queue to a higher resolution (PPQN aka ticks-per-beat) and not subordinated to the current session's anymore. - Although being deprecated to use, JACK Session support is hopefuly fixed, once again. - Better discriminate CLAP Plug-in specific note events and strict MIDI dialect event processing. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
