My pleasure guys! I hope it's been worth the wait.

I shall be away all next week and all kits paid up to and including 8pm (BST)/9pm (CET)/3pm US Eastern Time on Thursday 6th August will be dispatched on Friday 7th August. Any unpaid kits at that point will start shipping again from Monday 17th August.

Thankfully not too many to go now, but still no contact from a handful of those on the round 2 list.

Same here! It's a pleasure to have played a small part in such an awesome project.
Cheers John for making it happen. :hail:

If anyone is going to do another round of boats (especially in the USA), I would be down for one.

Received mine this afternoon.
Very fast delivery.
And what an excellent packing job. :wow: :wow: :wow:

Are there any PCB/panel sets left? I'm going to pull the trigger on the TTSH soon and want to build this to go along with it.

Not at present. There is a growing waiting list and more than likely to be another run at some point, but I'll be handing it over to one or two others to manage instead of myself.

The led-sliders from Mouser are red.(not possible to change colors)
There should be a possibility to change the led's.
Somebody who has a link or partnumber?

Thanks,

Please forgive my cross post, but I need to check something.

1. When you stop the sequence half way through and reset, then start again, does your sequencer play step 1, or does it actually start on step 2?

2. When you power up, does your sequencer automatically start running?

I'm not sure if my build is acting up or if the above is normal behaviour... everything else is working perfectly.

Thanks.

EDIT: Answered - This is normal behavior, my build is fine :yay:

Phew! Had me a little worried there too. I guess these oddities are just 'features'.

I did spot one glaring error in the ARP schematic diagram so hopefully there weren't any not so obvious ones.

Just messing - short example, crap audio - BUT IT"S ALIVE!!!! Mwahhh hah hah hah.

But watching my avatar at the same time is freaking me out :wink:

Thanks John, for a superb project & Simon for the Boat (who also happens to be a jolly nice chap)

Thanks Andy, you're welcome, and thanks for your help on the 3620.

A pretty cool demo actually. Nice to see & hear your own 2600 working too.

OK, so you've got your ARP Sequencer and TTSH... Now it's time for some fun sequencer processing, so stop all those Daft Punk/Moroder (and in my case, John Carpenter) fumblings, and let's see what else you can do with the 1601 :wink:

What an awesome sequencer this is. The layout with faders is imho better than turning knobs and all the possibilities for modular integration makes it a very powerful and creative tool. I've been wanting one for a long time and couldn't be happier. The prices for an original on ebay, etc are insane (2000-3000 €) so this has truly been the bargain of a lifetime. Thanks again for making this happen.

Wasn't aware about the reset/first step oddity until i tried to sync it to my daw and dinsync stuff, but that gave me the final excuse to order the e-rm multiclock box. It can be set up to skip the first trigger which should put everything back in perfect jitterfree sync.

Btw really cool tip from broadwave to use it as a vco, keep them coming. Im guessing here but some kind of crude triangel and sawtooth waveforms should be possible too. The fm input should give you vibrato when the sequencer is clocked at audio rate and the random switch should cause even more waveform mayhem. I'd expect that a portamento cv run thru the quantizer should turn into glissando, i'll def give it a try tomorrow. I've been experimenting a bit with using using the 3 gates to trigger different envelopes on my modular and even using one of them as a simple AR envelope by running it thru the lag processor on the 2600 or similar slew limiter.

Wow, great! I didn't think the sequencer was fast enough to do this. Thanks for the inspiration. :eek:
Now I'm even more looking forward to build mine. (Studio's down at the moment, so it'll have to wait a bit)

OK - so I couldn't wait any longer - I finished mine today! :hyper:

Everything worked from the start except a nasty bug on Gate 3. But I'm proud that I immediately took the right road to find the error and indeed it turned out to be that the pad for the 100 Ohm resistor closing off Gate Bus three didn't make contact. (lots of strange things happened when I switched gate 3 to skip, ha!) I had suspected that Bus 3 might not be sitting right level-wise, because the LEDs would dim when Gate 3 was switched on.

So it calibrated fine and works alright (did the "easy" fix for sw1. Works for me).
After playing around with the FM and PW inputs I now get it how several Depeche Sequences came to life! :mrgreen:
Funny, how the layout of a sequencer influences the way you work with it.

I have just found a workaround for the step 1 not playing on Start: Press Start/Stop and Reset together. I found it when I wired the footswitch out to reset in. So with every start via footswitch the sequence starts from step one and I noticed that this way step one is actually played.

Thank you Kipling and Satindas once again for this great project, it looks and works awesome! :tu:
