September 11, 2020 - Went public

treefallsound.com went live.  "Advertised" on two forums: DIYStompboxes.com & community.blokas.io

September 2, 2020 - Enclosures!

Feb thru August, 2020 - Covid Months
Did some redesign of the relay bypass.  Otherwise kindof stuck without a source for enclosure manufacturing.  Focused on software improvements.  Got friends to build units and give feedback.

February 22, 2020 - pi-Stomp Build #2 with enclosure

• Swapped location of Left and Right jacks (more intuitive)
• Improved signal routing to minimize noise
  

August 25, 2109 - First PCB Version

These functions working:

• Audio processed thru both Left and Right channels
• Headphone output works
• Bypass reed relays controllable via footswitch
• LCD shows current Pedalboard / Preset / Tweak param / Tweak value / footswitch mappings and enable state
• Each footswitch sends MIDI CC and toggles LED ring
• Tweak Knob sends MIDI CC and changes corresponding parameter when mapped. Display graph shows value.
• DIN and USB MIDI input produces MIDI CC and changes param
• Expression pedal input produces MIDI CC and changes param
• Top Encoder changes Pedalboard. Future software change necessary to change Preset.

May 8, 2019 - Mod a'la pi

4 knob, 2 footswitch.  Stripboard.  16 position encoder selects MOD pedalboard/preset. 

Arduino for sending MIDI CC to pi via USB with input from two assignable tweak knobs, expression pedal and DIN MIDI jack.

(shown without pi installed into 2x20 header)

April 5, 2019 - Proof of concept
