Velo delay

I really should have used this app a long time ago, I used streambyter in midibridge so I’m slightly used to the syntax, was reading through the university and tried the simple delay example, and got carried away. Added a 4 tap delay with velocity, and the option to offset the delay notes, also works as a chord generator.
heres the code.
**********Needs some work on the  lower notes maths instruction not doing as expected.


# StreamByter - Audeonic Apps

if load
set q0 Delay_ms 0 $2000
Set q1 Delay-ms 0 $2000
set q2 Delay_ms 0 $2000
Set q3 Delay-ms 0 $2000

Set q4 Velocity 0 $127
Set q5 Velocity 0 $127
Set q6 Velocity 0 $127
Set q7 Velocity 0 $127

set q8 Note_offset $-12 $12
Set q9 Note_Offset $-12 $12
set q0a Note_offset $-12 $12
Set q0b Note_Offset $-12 $12
end

# detect a note on or note off
if MT < A0
# clone the note with delay set in q0
# Assign I0 = M1
Math I0 = M1 + Q8
Math I1 = M1 + Q9
Math I2 = M1 + Q0a
Math I3 = M1 + Q0b

send M0 I0 Q4 +DQ0
Send M0 I1 Q5 +DQ1
send M0 I2 Q6 +DQ2
Send M0 I3 Q7 +DQ3
end
