Sequential Circuits Prophet T8 Keyboard Action Restoration

Published on Sep 15, 2013 New England Analog LLC·26 videos

"This video shows us restoring the keyboard and aftertouch mechanism on a Sequential Prophet T8. Not pictured here are the tightening of the key bushings and the calibration of the aftertouch and action capstans. This needs to be done for each note after the keyboard action has been restored. The results are fantastic if done correctly and the T8 action will feel light and responsive, not sluggish and quirky."

Prophet T8 Aftertouch Retrofit

"This is the second part of our video series on the Prophet T8. The first part dealt with replacing the badly degraded foam. This part addresses the replacement of all of the aftertouch boards with NEA T8 Aftertouch Boards. Our boards are a direct replacement for the original aftertouch boards, with identical multiplexing circuitry. The only difference is that we are using high quality, modern, FSR sensors which are superior to the originals. As the old sensors fail, they become less and less sensitive until the carbon is completely worn away. These new sensors will make your T8's aftertouch feel like new and the response will be even across the entire keybed. The complete set of replacement boards is $1100. The price is high because the sensors used aren't cheap and each board also gets hand assembled. If you'd like more information, or would like to order a set of boards for your T8 or Synclavier, please contact us."
