Can somebody please confirm that the mouser BOM actually includes all of the parts you need to build the yocto properly?
I cant seem to find a 15n polyester capacitor anywhere in the BOM which means I cant build the snare circuit and leads me to believe the 3 capacitors i put at C40, C41 and C42 in the bass drum circuit are incorrect because I assumed the .0015uf Nichicon included in the mouser BOM was what was supposed to go there.
I am not the most experienced when it comes to electronics but I have built many circuits before. I am great at following instructions when laid out clearly and have pretty fantastic soldering skills. Forgive me if any of my questions seem childish. I would like to build the yocto right the first try.
I need serious help. Mouser bom incorrect ??
arent that just the 0,015 uF ceramic caps by AVX? (mouser-nr: 581-SR215C153KAR) ?

Be sure to check the revised manual.

Yes there is the ceramic caps. This must be what is to be used. I think my confusion was because the build instructions where showing polyester caps and I was following the build instructions exactly and assumed thats what would be included in the mouser BOM.
Everybody's gotta start somewhere 
It's better to ask questions than assuming the wrong things and building something that doesn't work, or doesn't work as intended.
Substituting capacitor types is something that should be done with care. Most places it won't matter at all, even so called golden ears won't be able to tell. If it's in the audio chain it's possible that it will be noticeable. If you stick ceramics in, you should go with COG or NPO types as they have very low temperature drift. X7R is almost as good. In the end I don't think this matter that much in this part of the circuit.
A film cap alternative would be Panasonic ECQ-E2153JB for instance. However, just because it has the right lead spacing doesn't mean it is a guaranteed fit. Some PCBs are densely packed so it needs to be tested.
Keep at it! It's possible to substitute passive components with both this and that, even transistors can be switched to others if you're careful. Sometimes the substitution is simple - a 1N4148 is the same no matter who made it, sometimes it's a 74HC595, sometimes it's really tricky and maybe not the same, but will work anyway. Sometimes it's an honest mistake in the Bill of Materials.

thanks for the help! I appreciate the detailed explanation.
