Roland Jupiter-8 + TR-808 Trig Seq.

"Hi everyone!
TSF here. :)

This short video is featuring the Jupiter-8 arpeg. clocked to the TR-808 trigger out. I am demonstrating the 808's precise control over the arp in JP-8 using EXT on JP, JP-8s ability to be modified while the 808s triggers are being received and then further in the video after some editing of the patch I plug the 808 AC TRIG OUT directly into my mixer channel strip so you can hear exactly what JP-8 "hears" from the 808. It is a high amplitude signal.
If you do not have an 808 but wish to trigger the JP-8 or JU-6/60 or any other synth that receives trigger in, it CAN be done. There are several other great videos demonstrating this on youtube by other users. Also,, to trigger the JP (or other synth/drum machine) you will need a high amplitude sound or short duration "spike" kind of pulse from another source. Drum sounds seem to work well for JP-8, even a drum sound sent directly into JP from the Yamaha Motif6 triggered JP's arp.
Here is some information on the 808s trigger out:

808 has 3 trigger outs. They are CB, CP, and AC all of which are located on the back of the 808 which I show the camera when I am picking up the 808. Keep in mind these trigger outs will function simultaneously along side the actual (cow bell CB), (clap CP) and the (AC accent) function/sound. If you do not want to hear the sound along side the trigger, you can simply turn down the individual volume for each, a nice feature of the 11 sounds on the 808.

A 'TRIG' or Trigger is a high magnitude voltage or transient spike, 808 provides 3 trigger outs, each trigger signal is a positive 15 volt, 20 millisecond pulse. It is very loud and will peak a mixer channel easily as it did on mine.

Some ENV/ADSR settings to approximate the short trigger of the 808 could be suggested as:

(synth: JP-8) ADSR- A= 1mS-5mS, D=1mS-10mS, S= 0-100%, R= 1mS-10s
(Also keep in mind that the Decay time and Release Time on an analogue synth like JP-8 are the same parameter just placed at different sections of the ADSR or "Shaped control voltage".
A= 0 meaning the attack time of the ENV should be 0 so that there will be a quick instantaneous response once the key or other trig/gate is started/pressed. A- controls the amount of time required for env voltage to reach its max level after a gate signal is received.
D= 0 to 2 or to the setting that works best. The decay time controls the amount of time required for the voltage to fall from its level at the end of the end of the attack time to the level set by the sustain control.
S= 0%. there needs to be no sustain for a short sound. Sustain control determines the level to which the voltage will fall at the end of the decay time.
R= 1mS- release of the gate signal. The amount of time required for the voltage to fall to its minimum level after the release of the gate signal.

Please enjoy this simple arp/808 jam.!
