Sequential Circuits Model 800 Sequencer Demo

[@ozhalljr]

Keith, Great demo. I used to own a Model 800. Sold it to a friend who still has it. I recently acquired a Model 700 programmer :)

Guy you got to make more videos, the viewers you do have love your stuff.

The clock on the Model 800 runs at a very high speed (I believe it is 64 or 128 pulses per note), while the TR-808 can only supply 24 pulses per quarter note (through DIN Sync). You could sync the Model 800 from the TR-808, but the Model 800 would run very slowly. Clocking the other way around (syncing the TR-808 from the Model 800) could be possible, but then you would have to build some sort of clock divider circuit, or the TR-808 would run too fast.

I love learning about this. Love your videos. So logical and organized. Such a pure science. I really dig it.

[@krmelectronics]

I dig making the videos as well. Thanks.

Wow, great sequencer and demo! Thank you! :-)

Is this the model that Dave Smith designed before he began building the Prophet 5?

[@RudyAdrian]

Yep :)

[@ghostexits]

What a fantastic sequencer, I've never seen anything like it (where the pitch, duration and timing are all independently variable). I really enjoyed the synchronization demonstration also. I was thinking, why aren't there more sequencers designed like this for voltage controlled synths? But obviously, the polyphonic synths that came shortly after this sequencer probably made it seem somewhat obsolete to polyphonic players.

Roland MC-4, MC-8.

Nice!

[@krmelectronics]

Thanks!

A great demo, very clear and helpful. Well done! The "I Feel Love" bass part has a flat 7th in it, so it's C C C C G G Bb C. Makes it more bluesy and rocking! As I recall, it has a click out from the clock, to help you play in time?

[@videosuperhighway7655]

Cool product. How do I order these from you?

[@drswitch2]

I was wondering. If you have a sequence with a note duration. is it still easy to have it in sync by an external trigger? I would like to trigger the clock from the 800 with my TR808. is this possible? Tx

[@freisgreat]

hello have you got a schematic for the remote please?

[@FOCtv]

I just had an idea, in a newer video, you demoed the Roland CR78. Since the Model 800 can't just quantize a set of notes to a specific musical division (such as 1/16th notes), couldn't you use the trig out of your drum machine to input a gate pattern into the Model 800, like you did with the CR78? Then you would have all the notes locked to a grid, or whatever kind of syncopated pattern you've programmed on the trig out of the drum machine. I think you can get some cool results with the idea of separating the note values from the gate values!

[@FOCtv]

***** Cool! looking forward to that.

[@FOCtv]

Thanks for the demo. I am confused about something though. Since it records gate duration does this mean every note length is slightly different and quantization is not possible?

[@FOCtv]

***** I see. Thanks.

[@krmelectronics]

Sorry, I don't have the schematics.
