1. Jupiter Clone Demo
"Small audio demo from my jupiter clone project.

Latest additions are JP8's cross modulation section and locig for the preset buttons and display driver. There is no patch memory yet but logic for controlling patches and showing patch numbers on LCD's work.

Arpeggiator melodies are from Roland SH01 Gaias arpeggiator where I made arpeggiator patterns similar to JP8's arpeggiator."

2. Jupiter Clone Demo - Work Still In Progress.
"Small demo to show basic parts that are ready and how those work together.

Volume gets pretty high at the middle part of this demo while playing with PWM modulation stuff.

End parts song snippets :
Europe - Final Countdown
Van Halen - Jump
Synthartist69 - That 80's Sound (Adaption by me)"

3.DIY Jupiter Clone - Broken Date
"Jupiter Clones casing is now done and first boards are fitted in.
In this video three voices from total of four are in use. I still need to build last two oscillator cards to get 4 voice polyphony. Filter and VCA for the last two cards is ready but needs tuning.

DR-202 is sequencing midi notes to Midi to CV converter which controls voices polyphonicly. Additional 808 beats and bassline are audioloops that I added in video editor."

4. Jupiter 8 VCO clone
"Short video from my latest DIY build.
This video shows two DIY JP VCO voice cards build on veroboard. Each containing one VCO with saw, square and pulse witdh modulation. Together these two vco cards make one voice. SH101 sends CV to voice cards and GATE trigger to DIY VCADSR circuit.

These is a small error on the info text in the video. Originals NF510 fet is replaced with 2N3819, not with 2N3918 as mentioned in the video."
