LSP - Linux Studio Plugins
A plugin collection for sound processing
The best free FXs library
The official Zynthian V5 Kit have 2 balanced audio-inputs with independent gain-control ranging from -12db to +32dB. Read the full specifications here. You can directly connect a wide rage of input devices, like dynamic microphones, electric & acoustic guitars, piezos, line-in, etc. If you need more audio inputs, you simply connect your favorite USB audio interface and get all the extra audio input/output channels you need.
Zynthian supports the LV2-plugin standard and includes hundreds of audio-processing plugins. You can combine them as you like for sculpting the sound, recreating vintage landscapes or exploring new textures. You can have any number of FX-chains with flexible routing allowing as simple or complex configuration as desired.
If you are a guitar guy, you will enjoy the neural modelers included with zynthian:
They bring state-of-the-art, accurate emulation of analog gear like amplifiers, distortion, fuzz, overdrive stomp-boxes, etc. Literally thousands of models are freely available from Tone3000, that is fully integrated with zynthian. Choose a model for your favorite gear and get the tone you love with a few clicks.
If you like looping, SooperLooper is fully integrated, allowing to control up to 6 independent loops with instant record, overdub, reverse, multiply, replace, time-stretch, pitch-shift, and much more.

The MIDI-learning workflow is quick and easy. You can adjust the parameters you want from your favorite MIDI controller. Buttons can be assigned to presets (program-change), and knobs and faders to parameters (CC).
Regarding latency and jitter, the default configuration (<10ms) is enough for most players, but if you are looking for extra-low latency, audio configuration can be tweaked.
