@ -6,24 +6,40 @@ What we build next?
* 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
#### MK's Diode Ladder VCF
* ~$8 in parts, two tl074 op amps and otherwise a bunch of diodes and support
# 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
#### 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
#### MK's S&H
* not strictly a noise generator, but contains one?
* not strictly a noise generator, but contains one? see above
#### MK's three-color noise generator
* breadboard it
* spectrum analysis
* add more colors, if possible?
* more details TBD
# VCA
#### MK's VCA
Probably a straightforward build, one op-amp, four transistors and some supporting components.
# Envelope Generator
#### MK's A(d)SR
* breadboard it at least, to understand it
* decide if having D + R tied is a dealbreaker
#### 7555-based ["Fastest Envelope In The West"](https://www.schmitzbits.de/adsr.html) (bottom one)
* third iteration of a simple manual EG
* ~$7 in parts, depending mainly on whether 8+6 pins + hardware fits on shaek board or similar size perf.
