Hi, I recreated the 303 house classic with Sonic Pi using the TB303

I am new to Spi so bare with me 🙂  
The only thing I struggled with, are the slide effects from the real TB-303 which combines notes…  
Can I do this with spi?

Here is the code

```ruby
use_bpm 134
t = 0.25 #general sleep value
x = 0.25 #general release value
lfo1 = ()
lfo2 = ()
lfo3 = ()

live_loop :lfo do
  lfo1 = (range 80,130,0.5).mirror.tick #for cutoff
  lfo2 = (range -0.5,0.5,0.05).mirror.tick #for panning
  sleep 1
end

live_loop :resonance do
  lfo3 = (range 0.5,1,0.01).mirror.tick #for resonance
  sleep 2
end

define :t303 do |nte,rls,slp| #note, release, sleep
  use_synth :tb303
  play nte , release: rls, cutoff: lfo1, pan: lfo2, res: lfo3
  sleep slp
end

live_loop :riff do
  
  32.times do
    
    t303 :r, x,t
    t303 :a2, x*4,t
    t303 :a2, x,t*2
    
    t303 :r, x,t
    t303 :r,x,t
    t303 :c2,x,t
    t303 :r,x,t
    
    t303 :a2, x,t
    t303 :r, x,t
    t303 :a2, x,t
    t303 :r, x,t
    
    t303 :a2, x,t
    t303 :d3, x,t
    t303 :e3, x,t
    t303 :g3, x,t
    
    t303 :r, x,t
    t303 :g2, x,t
    t303 :r, x,t
    t303 :as2, x,t
    
    t303 :r, x,t
    t303 :r, x,t
    t303 :r, x,t
    t303 :as2, x,t
    
    t303 :r, x,t
    t303 :as3, x*2,t*2
    t303 :as3, x,t
    
    t303 :gs2, x,t
    t303 :r, x,t
    t303 :as3, x,t
    t303 :r, x,t
    
  end
end

live_loop :kick do
  sample :bd_haus, amp: 2
  sample :sn_dub, amp: 0.75
  sleep 1
end

```

It’s a good start to something, keep at it 🙂

You can make your code a bit cleaner by using rings for the notes and times, like so:

```ruby
live_loop :riff do
  notes = [:r,:a2,:a2, :r,:r,:c2,:r, :a2,:r,:a2,:r, :a2,:d3,:e3,:g3,
           :r,:g2,:r,:as2, :r,:r,:r,:r,:as2, :r,:as3,:as3, :gs2,:r,:as3,:r].ring
  releases = (ring x,x*4,x,x)
  times = (ring t,t,t,t*2, t,t,t,t)
  
  32.times do
    t303(notes.tick, releases.look, times.look)
  end
end
```

This is so much fun!

Nice!

but you never used bd\_haus while you loaded it in the beginning

It works as a charm 🙂  
This is the complete sequence

```ruby
  notes = [:r,:a2,:a2, :r,:r,:c2,:r, :a2,:r,:a2,:r, :a2,:d3,:e3,:g3,
           :r,:g2,:r,:as2, :r,:r,:r,:as2, :r,:as3,:as3, :gs2,:r,:as3,:r].ring
  releases = (ring x,x*4,x, x,x,x,x, x,x,x,x, x,x,x,x, x,x,x,x, x,x,x,x, x,x*2,x, x,x,x,x)
  times = (ring t,t,t*2, t,t,t,t, t,t,t,t, t,t,t,t, t,t,t,t, t,t,t,t, t,t*2,t, t,t,t,t)
  
  32.times do
    t303(notes.tick, releases.look, times.look)
  end
end

```

hi @hyprboy

would you please use 3 backticks to colorize your code ?

Yeah, I’m looking for a different beat, maybe trap, not sure yet. 🙂
