Pedal Steel Guitar Synthesizer

This is a sound application to mimic playing a pedal steel guitar. It uses my sound library liborza and currently supports JACK as an audio server.

Features

• Change string notes and number of strings
• Change semitones
• Change pedals and what they modify
• Change number of octaves
• Effects rack supporting LV2 audio plugins.
• Basic square, saw, and sine wave outputs.

What's to come?

• Manipulation of any audio signal as a note on the guitar
• Custom tonebar image
• Custom colors or image for frets

Usage

Keyboard and Mouse

• 1-9 string notes
• mouse to move tonebar / raise or lower pitch
• Set characters in pedal editor, but the default is a,b,c and various others for the knee levers modeled after this website https://www.steelguitar.com/tunings.html

Midi

You can connect to the app via midi and play from an outside program or external device. OrzaSteel will connect to all midi devices on startup. Controlling it works as follows.

Eventually I plan on being able to configure these, but they hardcoded for now.

Notes

• 24(C1) - 47(B2) = String on/off
• 48(C3) - 61(B4) = Pedal on/off

Control

• 14 Pitch or tonebar position
• 15 Volume control

Jack

Starting the app will start jack. I recommnend starting it elsewhere, ./bin/jack_startup.sh is a sample startup. Midi will need to be enabled.
