Beatmaker’s sketchbook is an alternative to commercial sample based sequencers/grooveboxes with a big difference – it is 100% Open-Source.
Its core is a Teensy 4.1 microcontroller with 16 MB additional Sample RAM (~3 minutes of samples in memory) and uses a Micro SD-card as permanent storage.
Beatmaker’s sketchbook houses a microphone, a fader, four rotary encoders, 24 keys for two octaves, 12 functional buttons, a display and a via USB rechargeable battery. It can sample through a line-in or the built in microphone, playback via headphones or the line-out connector and communicates with external devices via MIDI.
Beatmaker’s sketchbook comes in different flavors:
- Beatmaker’s sketchbook mini
- Beatmaker’s sketchbook custom and unique handmade devices
- PCB “mainboard” to use it as the base for your own project
