Patchblocks helps you build your own synthesizer. With the Patchblock editor you can develop your own sound, either by editing some of the existing patches or create your own based on a variety of DSP building blocks. Once you created your program, you can upload it to the Patchblock with a USB cable. You can change your program as often as you want. Once programmed the Patchblock does not need a computer. It doesn't even need a power supply, as the USB-rechargeable LiPo battery lasts for over 10 hours. You can use the Patchblock as a standalone sound generator. It can play sequences of synth-sounds, drums, or just act as an exotic noise machine.
