CR68-M-TMG DIY-retrokit for Roland's CR-68


2019/05 - CR-68-M-TMG demosong Published on May 21, 2019 Stereoping

"The CR68-M-TMG is a DIY-retrokit for Roland's CR-68. 'M' stands for Midi as all voices can be triggerd via Midi - including Accent. The 'TMG' describes the cooler part - the PCB also holds the three missing instruments of the big sister CR-78 which the CR-68 normally lacks: Tambourine (TB), Metalbeat (MB) and Guiro (GU). All voices were carefully recreated based on original schematics. Tambourine is available as longer and shorter decay and Guiro in high and low pitch. Each of the 3 drumvoices uses a special inductor to build a very steep bandpassfilter definately needed to form the characteristic timbre. We've given a little batch of these inductors into production on rare, old winding machines to get the perfect sound.

This mellow demosong shows details of the PCB and electronic parts as well as some footage of the CR-68 itself. The drums are - of course - coming from a CR-68 equipped with this retrofit. The song introduces the 3 instuments one after the other. Typography and visual helpers like realtime analyzer and oscilloscope will guide you to easily identify the single TB/MB/GU sounds in the mix.

The CR68-M-TMG retrokit is available now in the stereoping shop. Production run is limited due to these special coils."
