 Pretty confident we do these in this order next.
 
 ## Sequencer
-#### Baby 8
+#### MK's 5-step sequencer, expanded to baby 8
 
 * Breadboard MK's 5-note sequencer.
 * Compare to online 8-note sequencers (baby 8)
 * Either build online 8-note schematic, or extend MK's 5-note to 8-note.
 * padding MK's out to 8 notes means roughly $16-20 in parts, depending on PCB choice
 
+#### Bergman's 10-step sequencer
+
+* can do up to 10 steps with the hardware to support it
+* 10-step mode is ~$16 in parts, depending on which are actually needed
+* big board, requiring one 8-pin, one 14-pin and one 16-pin IC
+* maybe more stable than MK's?  test this
+* includes weird 8V linear regulator for the hex inverter - maybe save a bunch of effort and pins by using a single tl074, with two as needed and one as schmitt trigger?

 ## VCF
 #### MK's Diode Ladder VCF
 * ~$8 in parts, two tl074 op amps and otherwise a bunch of diodes and support

 ## LFO
 Lots of options for this one, but many people have at least two LFOs anyway.
 
+## Quantizer
+Something to take CV in, round it to the nearest 1/12th of a volt (or whatever, if it's digital), and send it back out.
 
+#### Arduino + DAC

+* https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer
+* https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file
+* uses an arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the MCP4922 DAC (others may work).
+* Probably can build our own based on this and/or Hagiwo's quantizer, if going digital

+** arduino nano clone (atmega 328p), 12-bit dac (mcp4726) and small amounts of supporting hardware

+#### MK's quantized arpeggiator
+
+* could extract just the quantizer part
+* needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a tl072
+* arpeggiator needs a 4040 binary counter, but separated quantizer might not

 ## Sample & Hold
 #### MK's S&H, though maybe move the noise generator to a separate module?  If possible?
