So I've been trying to create some patches. One sound I would love to make is the arp'ed / fading sound from Armalyte. I know how to use the arpeggiator but I'm wondering how to do the "crunchy fade" bit (Sorry for lack of better descriptors). I'm guessing the LFO is involved in some way... any ideas? ( )

Well, they swapped it for a new one. It measures a healthy 14V with the meter and now the Sammich powers up fine!

It's this one: http://www.radioshack.com/product/index.jsp?productId=3832491 is there a possibility it won't show 12V unless there is a load on it?

It doesn't have any switches. I wonder if something failed in the unit. I guess I'll take it back to Radio Shack.

I was happily using my sammichSID the other day jamming out with a friend. Then, today I tried to power it up, and... nothing. I checked the power supply (12V 500ma regulated enercell from radio shack) and I only get 6VDC. I don't get anything on AC. Does this sound correct or should it be reading 12V? thanks.

I figured it out, it was my audio cable actually. The SIDs are actually identical in volume. Thanks.

One odd thing i've noticed is that on the poly patches it seems that SID #2 is much much quieter than SID #1. Is it supposed to be that way?

Hey all, I finally got it all working and the patches downloaded. I used some rubbing alcohol to remove the flux mess I made then I resoldered all of the iffy joints and... et voila.. I HAZ SAMMICH! Woohoo! Happy New Year!

I'm almost done with my sammichSID. It passed the voltage checks and continuity tests. I added the IC's and powered it up. I got MIOS downloaded and tested out the first patch. I put the case together. I tested some patches with a MIDI keyboard. Everything was working okay, for a few minutes. I am having an issue where it turns on and sometimes actually boots up correctly. However, very shortly afterwards the LED's act strange and the rotary encoder stops working. None of my solder joints look bad, but they aren't all exactly that great. I tried to use some flux for the pins on the connections between the two boards and it actually seemed to make it stick worse. I think I used too much likely. Anyway, I suspect either a loose pin or a bad solder joint but I'm having a hard time detecting it. Are there any good tests or ways of finding this? thanks to Wilba who's already helped me quite a bit.

Question answered by Wilba. the pins right next to each other are connected, so it doesn't matter exactly. It's there for spacing. thanks.

I'm trying to solder the ceramic capacitors in and each slot has 4 sets of dots on the board, yet only 2 legs for each cap. Which holes am I supposed to solder them into?
