About this app

JiniSynth turns a phone or tablet into an instrument you can take to a gig.

A SET LIST, NOT A MENU
Put tonight's sounds in order - piano for the first song, organ for the second, a
pad under the ballad - and move between them with one tap, a footswitch, or a
program change from your keyboard. Every sound in the set is loaded before you
start, so the change is instant and a note you are still holding rings out
instead of being cut off.

YOUR KEYBOARD, CONNECTED
Bluetooth LE MIDI and USB MIDI keyboards. Velocity, sustain pedal, pitch bend,
modulation and aftertouch all come through. Assign a CC to step forward and back
through the set list, so a footswitch changes the sound without you looking down.

SOUNDS THAT ARE READY TO PLAY
A full General MIDI bank is built in - 259 sounds and 11 drum kits - with a
starting set list already laid out across the families: piano, electric piano,
organ, guitar, bass, strings, brass, pads, leads and drums. Fifty more SoundFont
banks can be downloaded inside the app when you want a different piano.

LAYERS AND SPLITS
Stack up to eight sounds on one key, or split the keyboard so a bass sits under
your left hand and a piano over your right, with the split point where your hand
actually is.

BUILT FOR THE STAGE
- A level for each sound, stored with the set list. Turn the organ down for
tonight's room without changing it for every other night.
- Transpose per set list, so a song taken down a tone does not follow you into
the next set.
- Keeps playing with the screen off - the audio and the MIDI link stay up.
- A panic button for the note that will not stop.
- Low-latency audio with nothing allocated on the audio path, so the app is not
pausing to tidy memory in the middle of a song.

FREE, AND WHAT UNLOCKING ADDS
The free app plays the whole bank and connects to your keyboard. What it keeps
back is the set list: two sets, holding three sounds each. Unlocking gives you as
many set lists as you have nights, and as many sounds in each as you can reach.

PRIVACY
No account, no sign-in, and no server of ours. No advertising, no analytics, no
tracking of any kind. Your set lists stay on your device.
A stage synth: put tonight's sounds in a set list and switch without a gap.
