🧵 So, on my journey to live #PitchShift on #Linux with an #audio #plugin, I found #SpectralShift. This one is very good I think. However, it has too much latency for live use, so it's more for mixdown.

The old #MaPitchshift serves as an example for one of the reasons why #LinuxProAudio had a bad reputation in the past: It's practically useless. It does pitch shifting, but it only shifts by some magic floating point number which has no easy-to-handle relation to musical terms such as semitones or cents. The latency depends on the window setting, yet it is possible to sabotage the thing completely by nonsensical settings.

So I asked ChatGPT and it said the ratio is 2^(Semitones/12) – keep this in mind and your calculator ready. 🤪 This is actually sort of correct.

Turns out that the shifting of #MaPitchshift is too inacurate for musical use with a window size suitable for live use. So, giving up for now, back to outboard, my 21-year-old #Lexicon #MX200 is way better.

#LinuxAudio #vst #vstplugin

I found another interesting audio #plugin for #Linux: #reTuner claims to do good pitch-shifting for instruments generally too low or too high. Like 440Hz to 432Hz shifting.

There is a .deb package, yet unfortunately, the plugin installs to a non-standard place.

I decided to symlink /usr/lib/x86_64-linux-gnu/vst3/KV-reTuner.vst3 to /usr/lib/vst3 instead of adjusting plugin paths in all my plugin hosts.

I don't have an urgent need for it, but I'm sure I will use this at some point.

(Actually I am looking for a possible replacement of the pitch shifter in my Lexicon MX200, which I still do love… yet the ADCs of the Lexicon are a sad story, and the old Boss compressor sitting in that rack together with a cheap Alesis tube preamp isn't that reliable any more.)

Pitch Sequencer Turns Tascam Tape Deck Into Instrument

The cool thing about magnetic tape is that by varying the speed at which you play it back, you can vary the pitch of the output. [Issac] decided to take advantage of this, executing a fancy digitally-controlled pitch mod on his Tascam Porta 02 tape deck.

The build uses a Raspberry Pi Pico, which employs PWM to control the speed of the tape drive's motor. This is achieved with the use of an NPN transistor driven by the PWM output of the Pico. This allows accurate control of motor speed, and thus pitch.

With that sorted out, the project was fleshed out with an OLED screen and a rotary encoder. These allow various patches or scripts to be run on the Pico, controlling the motor speed of the tape player in various ways. With a bit of work, [Issac] was also able to create a function that converted MIDI note values into PWM values that determine various motor speeds.

The natural thing to do next was to put in a tape with a looping sample at a set pitch, and then vary it in a sequence controlled by the Pico. The 8 steps of the sequence can be manually set with the rotary control, and in future, [Issac] even plans to add a real MIDI input, allowing the system to act as a monophonic synth.

If you prefer other routes to pitch shifting shenanigans, check out this project. Video after the break.
