vibro

An instrument controlled by computer keyboard and mouse.

Building

Just run make. It produces an executable vibro on Linux, or vibro.exe on Windows.

Note on Windows the compiler x86_64-w64-mingw32-gcc is required. (Otherwise you have to change in the Makefile.)

Features

• Expressive features! (see Controls)
• You can load in samples!
• ADSR envelopes!
• Sound recording! (doesn't work for samples unfortunately)
• Additive synthesis (under the sine instrument)

Global controls

• SHIFT-LEFT/RIGHT to switch between instrument and note mode
• TAB to toggle fullscreen

Play mode controls

• LEFT/RIGHT to change instrument

• Z S X D C ... , L . ; / are the notes

• 1 ... 0 for global volume control (only applicable for solo mode)

• Move mouse left/right for local volume control

• Spam SPACE for vibrato. How long you press it controls depth, how fast you press it controls speed.

• Left/right click to temporarily adjust octave

• UP/DOWN to permanently adjust octave

• Scroll to pitch bend

• Move mouse up/down to gliss

  • Precise glissing: while holding down current note, press the note to gliss to while moving mouse up/down

• CTRL to toggle chord mode. Multiple notes can be played at once! (Note autogliss isn't supported)

• ALT for drop effect

• ` to record

• For right handers, I recommended the mouse be placed to the left of the keyboard.

Instrument mode controls

• Navigate using arrow keys
• For text fields: only BACKSPACE and DEL (to clear entire field) are supported
• For value fields (e.g. pitch modifier): use left/right arrow keys for coarse changes, mouse scrollwheel for fine changes
• Press ENTER to carry out certain options (like ADD/DELETE in the multisample submenu)
