***I finally got finished with my Nava, and seems to be alive and kicking, sequencer-wise, but have a fair few instruments that are either not working, or just clicks.
I've split this up into separate threads for each instrument, hopefully to help other people**

So my kick drum is only outputting slight clicks at the moment - what should I test first?

I've socketed all ICs, and the M5218Ls all seem a little loose, so I'm going to bend the legs a little more to get them to make contact, I'll report back if that makes a difference.



In case it is helpful to troubleshoot where I've maybe used the wrong component somewhere, I had the following components left over at the end (the numbers in brackets were the amount that were initially supplied, according to the mouser bags):

2 x 0.01uF Film (22x)
5x .1uF Film (7x)
1x 1N4148 Diode (95x)
4x 220R (8x)
1x 10K Resistor (138x)
2x 1K resistor
2 x 603 transistor

Hmmmm just playing around and I've found that if I push on one of the M5218Ls then I get a nice kick.

Just crimped the pins slightly in order to get a tighter fit, but it's still very temperamental - the slightest touch on the IC will make it stop working and need jiggling back into place...

Also, out of the main mix, the kick is really really distorted - like turning the volume pot up to 9'oclock (7 o'clock is zero) and it sounds mega loud through the main mix. Individual out it's fine... This might be where I used one of the incorrect values of resistor?

Solder the M5218L in place. Take you time and solder 1 pin at the time, with a small pause between, if you are concerned about overheating.

Couldn't face the idea of unsoldering all the sockets, so I've just soldered all the M5218L's into the sockets - no more flakey bass, but still way too loud through the main mix - I'll make a new post for that..
