I visited during my three of SuperBooth Berlin the booth of Patchblocks. These machines are little Synthesizers with only a few encoders and buttons. You can design your own Synthesizer, effect processor or even a little arpeggiator with a free editor software. For using it as arpeggiator, you need a special Midi module which you can connect directly to the Patchblock. The price point for this product is very interesting and affordable for all musicians.
It’s cost around 59 Euro and offers a lot of different sound possibilities, from a drone Synthesizer to a normal bass Synth. The build quality is great and doesn’t feel like 100% plastic and the sound is also very good for this interesting price. Here is an interview with the people behind this nice company from Germany.
