Midi Controller for Alpha Juno 1

hi,

i plan rebuild old programmer (pg300) roland. programmer build alpha juno , send midi sysex alpha.
i wrote simple code had found in www.
i build simple midi in circuit .
the fowling code includes 3 analogin. 1 select midichannel , others control cutoff , resonance. code works.
thats first step of project , question: think code ok or can more simple?

the next question: arduino uno have 6 analogins need round 35 , more?
i have use multiplexer or there other way have more analogsins?

code: [select]

i have use multiplexer

yes have use multiplexer.

you think code ok

remove commented out delays , learn use functions make code easier follow.
