 What we build next?
 
-# Sequencer
+# Near Future
+Pretty confident we do these in this order next.
+
+## Sequencer
 #### 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
-# VCF
+
+## VCF
 #### MK's Diode Ladder VCF
 * ~$8 in parts, two tl074 op amps and otherwise a bunch of diodes and support
 
-# VCA
+## VCA
 #### MK's VCA
 
 * Probably a straightforward build, one op-amp, four transistors and some supporting components.
 * ~$6 in parts, needing only one 74 and support components, so tiny PCB should be fine
 
-# Sample & Hold
+# More distant future
+Less confident about the order or selection of these, though we do know we need a noise and envelope generator and a S&H would be nice.
+
+## Sample & Hold
 #### MK's S&H, though maybe move the noise generator to a separate module?  If possible?
 * full unit is ~$8.50 - $10 in parts, mostly down to PCB for holding three chips (two 74s, one 72)
 
-# Noise
+## Noise
 #### MK's S&H
 
 * not strictly a noise generator, but contains one? see above

-# Envelope Generator
+## Envelope Generator
 #### MK's A(d)SR
 * breadboard it at least, to understand it
 * decide if having D + R tied is a dealbreaker
