Jamm Pro (spiracy) coming together of music.

Jamm Pro is a music production and remix APP for I-pad, and the only digital APP I’ve used in my digital music since 2012.  

Matt Black and Jonathon Moore are two halves of Coldcut, a music production and performance duo that have been at the seeding edge of electronic dance music culture for four decades. Besides their musical output and live DJ performances, Coldcut have consistently produced tools made for DJ’s, both analogue tools, such as the 12” vinyl–DJ Toolz–series from 1993. 

JP is a part of a lineage of open-source tools for independent music producers and DJ’s. Matt Black in particular has helped manifest this Coldcut ethos in APPs aimed at the I-Pad touch-screen interface, intuiting how the innovations made at Apple could be repurposed for music production and performance. Accordingly, with each major update to the I-Pad comes updates and extended functionality of the APP. This lineage of the development from Coldcut–and by association the groundbreaking independent label NinjaTune–is important to me as it distinguishes them from many other APP manufacturers by their consistent, core artistic values.  

A prospiracy is the coming together of forces for the betterment of all parties. What I see as the challenge or aim of the game with Jamm Pro, is both playing and creating TunePacks, seeking harmony and coherence, searching for the perfect beat. Jamm Pro forces anybody with ears to reconsider musical genres and try to figure out where one spills into another. Make it new, make it cohere.

There’s a host of instructional videos and demonstrations at Youtube, plus the APP itself features a detailed manual and on-screen “help” overlay which I found very useful. Matt Black does a weekly live Jamm Cast under the Pirate TV moniker, broadcasting on Twitch, Youtube, and Mixcloud where you can witness Matt hammering and pushing the APP to the outer limits, plus soothing visual candy and positive news items blended in.
