The following current Oakley projects use the DIP version of the LM13700N:
COTA (5U)
SVF (5U)
ADSR (5U)
ASV (5U)
Croglin (5U)
TSL (5U)
DSL (5U)
Discontinuity (5U)
Equinoxe (5U)
VC-LFO (5U)
VCO (5U)
SRE330
DCR320
It may have been easier to list my projects that don't contain the LM13700.

Over the next couple of years I will update some of the above list to use the V2164/AS2164, or discrete alternatives.
