    Notes

    The PMI SMP-10 was a part I had ready access to. A National LM398 or other monolithic sample and hold chip could be substituted, with appropriate pinout adjustments.

    Although I didn't include it, a welcome modification would be to have the output of the SMP-10 drive a pot-capacitor-voltage follower combination for adjustable slew limiting and portamento.
