Elka Wilgamat, Oberheim DX and Powertran Transcendent 2000 in sync

video upload by ohm_studi_ohm

"Since I just finished adding DIN SYNC24 to my Elka Wilgamat I decided to hook it to the Arturia Keystep pro and further added an Oberheim DX and a Powertran Transcendent 2000 to the game.
Playing with the Wilgamat accompaniment part brought a known melody to my memory so temptation was high to follow this path...

The Transcendent can be seen in another video i made earlier this month. It was modded to add a sub oscillator and also to correct the peculiar CV/Gate it originally used in order to use it in a standard CV/gate environnment. It's now working fine when controlled externally as you can hear.

If you want to add sync to the Wilgamat there are 2 issues you need to adress:
- the unit needs 4ppq so unless you have a device capable of providing such a clock frequency you need to convert the more conventional 24ppq to 4ppq.
It's actually very easy to do by using a single 4018 chipset, which can divide by 6 the incoming frequency
- second issue is that the clock on the WIlgamat ask for negative pulses so you need to convert the positive pulses to negative ones. I used a single op amp to do that (TL071)"
