Machine Collective has announced a public beta of its new modular music controllers:

The picture above shows our final prototypes. We made the sides from thin laser-cut acrylic so it’s easy to see if everything fits. The side panels of the final prototyping modules will be made from a high tech aluminum sandwich material which is also thin but much stronger than acrylic.

The picture above shows a few different configurations, which are, from left to right:

• Rotarypot 16 – 16 x panel mount 10K rotary potentiometers
• 4.5? LCD – for pal/ntsc video signals
• Monome 10h – for monome keypad kits
• Slidepot 16 – 16 x 10k slide potentiometer with 30mm travel
• Spark 16 – for Sparkfun silicone keypads with support for RGB leds
• Slidepot 6 – 6 x 10k slide potentiometer with 70mm travel
• Patchbay 25 – 25 x High quality banana jacks, can double as body contacts
• Toggle 16 – 16 x panel mount SPDT toggle switch
• Rotarypot 4 – 4 x panel mount 10K rotary potentiometers
