Re: Ryk M185 Sequencer - per step repeat and gate mode

Hi Ryk, Great price :-) For sure interested in two kits. I'm now looking for a case, and the 4MS POD60 looks like a candidate. Do you know the depth and power consumption? Thanks. Hello Thanks for the comments. Here are the power consumption specs: +12V - 75mA average, 110mA peak [ in some menu pro...

Re: Ryk M185 Sequencer - per step repeat and gate mode

Looks great Ryk!

I'm in for one or two (depending on final price).

What size is the panel?

Both feedback signals (paths) return and mix on the input buffer. Feedback send is before TAP1,2 pots, so any feedback level you modify will affect the input signal. Because feedback level are summing, you should lower the feedback levels if you want to use both in the same time. With a single tap,...

I don't really have a pony in this race yet, as my pcb set is still waiting to be built, but will add this: you have an awful lot of chip substitutions going on there. My experience has been that sometimes those will work, but sometimes they don't. Normally, if I need to make a substitution, I'll d...

I'v built tens of units starting from trimm values adjusted like in the manuals and adjusting a bit the longest delay time. (rare beats). So I think something else is wrong, it's better to check the clock line if you have clock from minimum o maximum 200khz-1mhz. Look at the schematics and test thi...

Does TIME and "TAP LEV" have influence on the pitch of the nboise you are hearing too? I might have the same problem, but its not noise its clearly the LM13700 OSC which are problebly the "clock" for the TAP, but why do they "bleed" into the audio?

Thanks for the PW resistor report :tu: I still have my RS boards unpopulated, so good information for the future. I did build Logicgates version in 2016 and used that time the resistor values from Benjamin AM, I assume these changes will also work on the RS boards? Sorry to bring this up so late in ...

Hi Patrick,

What is the brand/ model you use? I'm now preparing an order for Reichelt, do you a link maybe?

Thanks :tu:

Before selecting a new transistor did you have a try adjusting R328 (cf picture below). Otherwise Q86 is the 'noise' transistor (cf picture below). Thanks, yes R328 is maxed. Just swapped Q86 and placed a socket in there. The two other 3392's I have are of the same level. Maybe I should have gone f...

I have one MME running with 1N4148 - and its working just fine and sounding great. Looking at the schematics, I don't think the type of diode makes a huge difference. Even Moog substituted this diode several times as pointed out a few posts back. My second MME will be built with the 1N457A (which o...

Hi Julien, Finally sourcing my parts (via Mouser & Tayda and prefer to order all there) and wondering about some substitutions: • 1N458A is not stocked at Mouser right now, can I order the 512-1N457A or even use the 1N4148? • Cannot get the right values trimmers for 25R & 2.5K, can these be substitu...
