you mean IC305 right? This is normal. As long as you have the heatsink on the part it will get hot but is ok. The surface of the IC can get to 80 degree C and above, but will still be within spec for the part. This is the power supply for the whole x0xi0 circuit, including most everything on the top PCB, so if you disconnect pad D (12V to power circuits) it will cool down. If the heatsink gets over 120 degrees C then that would indicate a problem.Heating of IC304
ok, I will listen to the sample and go from there.Poor bass sound
This is probably because the attack of the envelope generator eliminates the clicks because it is set to a slower setting. Even at the minimum setting the attack time is a few milliseconds and could be enough to eliminate the clicks. Do the clicks also go away if you adjust the VCA attack time to a higher setting?Clicking of VCA.. It gets better if i switch on the envelope2 vca depth a little bit.
The noise circuit outputs a pseudo pink noise. As long as the filter overdrive switch (Filter OD) is off you should hear the noise at about the same relative level as the VCO's. If you turn the VCO's down to zero then turn the noise up you should hear the noise pretty loud - typical white or pink noise. Sounds liek maybe it's not right. Maybe you can record a sample of this too.noise generator
From what I see you should be able to test it but few connections would need to be made temporarily.Once I finish the x0xb0x build, I want to stop and check that all is working properly before starting the x0xi0 mods. Will the x0xb0x still work correctly, even with the part substitutions that I have made, and in particular, the part deletions? I *have* connected TM4 and TM5 (with wire).
I will get to this asap. My lab is not set back up yet in my new place but should be shortly.On Top of that i checked all PAD's on IO and Top xtention. Pls can you check if the values are right. Thank you.

The output of the VCF is very low, I want to say ~20mV or something along those lines. You may be a-ok. I would go ahead and move on to the VCA, double check everything and then listen to the signal at pin 3 of the volume pot (or do as described in x0xb0x build manual).So I did this (installed R62 and C17), but am getting very low output on the VCF test when probing the pot
