Hi Julian,

Would it be possible to supply some way of mounting the PCB to the Euro front panel as part of your panel kit offering?

Thanks

David

That panel Julian is beautiful. The new cutters are definitely a good investment.

Nice one Ryk.

Now I just need a couple of panels and some time to put it all together.

Hello

Julian the panel looks great, very neat.
What radius cutters are you using on the cut-outs ?

More PMs sending out this weekend.

PS A few people have dropped out of ordering, so if anybody
wants some extra, let me know.

I'm really late, I know Embarassed

I would be in for one PCB, one PIC and one set of switches in case anyone is bailing out. If not, I'm hoping for another run.

EDIT: Just sent an order to Ryk, there are still some left. Thanks again!

Does anyone know the current draw for this sequencer?

Euro panels for both software revisions (v2.0 and v2.1) shown below -

Now you're making me seriously think about going for a Eurorack panel. Wink

Very tasty. Thanks.

Is this what C6 (330N Poly) is supposed to look like?
The one's I have are 100V, is that ok? They look a bit out of place to me.
I just wanted to check before soldering them in.

Thanks Rik

Are there any switches left over from the group buy?

Funky40 · Posted: Wed Nov 25, 2009 1:23 pm Post subject:

got my package, thank you ryk !

Question:
there was the speak back then that 2 Sequenzers could be chained.
would this need any changes on the frontpanel ?
additional Jacks ?
or does it need to be chained internally while building.
i definitly like to have a 16stepp unit, preferably patchable and not hardwired

Hello,

I have just finished one of these sequencers, but seem to be have a couple of problems.

The sequencer works, all modes seem to work too (ping pong, random, stage CV etc.) but it does not output CV, when I connect it to a VCO the VCO just drops a couple of semitones. Also there is no Gate output, and the Run/Stop button does not work either (all other switches work). IE it won't start under its own clock.

I couldn't find R/S on the PCB, so I connected the Run/Stop button to S/S - maybe this is the problem?

I have taken some measurements, and the sequencer is definitely sending CV back to the board, I have followed its path as far as Q15, but I got a bit lost there to be honest - the measurements at Q15 are:

S = (whatever the sequencer is sending from CV pots)V
G = 13.8V
D = 0V

If these have any importance. Looking at the board the Drain of Q15 is leading to the portamento pot, which is not receiving any V's either.

I'm sure its just something silly I've missed but I've double checked everything, and I'm not sure where to turn without the schematic...

Any thoughts would be most appreciated!

Well, I spent a bit more time on it last night, and replaced a few bits n bobs, and now it is working really well, a great sequencer, thanks Ryk!

BUT.. the internal clock still does not work, I cannot get it to start - is S/S the correct place to connect this switch on the board? (As I said I can't see R/S)

I don't see myself using the internal clock much (if at all) but it would be good to get it running...
