[sdiy] Best AVAILABLE OTA for building new designs?

[Dan Snazelle]

imagine someone asked you to make some new synth modules.
then imagine that the last time you did so in any quantity above one---  it was 2017.


I am trying to get a handle on what the parts landscape is like now for cost-effective CV control. Back in 2017 the lm13700 was really the only available OTA . I was just starting to work with the ssm2164 at the time but never used it extensively.

In the interim I have built synth circuits but only in quantities of one where cost was no object and I was able to rely on my own extensive parts supply.


So my question is this-- if I am thinking about design for manufacturing—what do you think the best option is?

Has anyone tried the quad ALFA OTA? Is it even readily available? Same for the new SSM2040​.

OR would you just use the 2164 instead?
OR would you just try to make discrete OTAS out of say the  BCM856DS //BCM847BS

thanks for any and all opinions on this.
