Dear Sonic Pi’ers,

It is time for challenge number 3 😃

This challenge is dedicated to vinyl record speeds.

Instructions:

1. Choose a vinyl record speed - 33, 45 or 78 rpm. Your song BPM must be a multiplication of your chosen rpm speed. So, for example, if you choose 45, your song BPM must be either 45, 90, 135 and so on.  
You may use the built-in synths and samples or use external samples; it is up to you.  
The length and genre is also up to you.

2. Post the code and audio links (Youtube/Soundcloud/Bandcamp, etc) in this topic.  
Tell us about your process and/or what inspired your music, if you want.

**The deadline for this challenge is 31st December.**

Code and audio links will get added to the [challenge repo](https://github.com/binarysweets/sonic-pi-monthly-challenge/)

https://w.soundcloud.com/player/?visual=false&url=https%3A%2F%2Fapi.soundcloud.com%2Fplaylists%2F1182643831&show_artwork=true

Happy coding 💻

That is very cool. Now I start to see what this challenge is about.

That’s weird. Apart from the deck switches, it’s just two standard live loops.  
Could it be the bitcrusher fx inside the deck2 loop maybe?

Here is my contribution. OK, not vinyl but shellac 😄 The volume is a bit low, they didn’t have electric amps back then, you’ll have to turn up after listening to @binarysweets DJ thing. That doesn’t seem to use too much CPU on mine btw

Apparently a tight loop that repeats every 0.25 beats at 78 rpm/234 BPM is what does it for me… (45 rpm works, but there are constant ‘Timing warning: running slightly behind’ messages). This is on a Windows desktop, it may work differently on my macbook, haven’t tested it there 🤷‍♂️

I have finally managed to have a bit of time to do something for one of these 🙂 Here’s mine:  
(With apologies to any native Irish speakers out there 😅)

PS. If you _do_ know Irish, I’m actually kind of curious about the words and phrases they are saying on the recording - feel free to translate for me!

Here is an entry from me. I picked a bpm of 2 \* 78 to meet the challenge requirement and thought a festive offering would be appropriate, so here are two verses of the Carol of the Bells arranged for Sonic Pi. I decided to spend quite a lot of time adjusting the volume level of the individual parts as they play, using the “at” command to trigger the changes, and fx :level wrappers to do the adjustment. I also added two further fx :level wrappers to balance the first part against the remaining three which used a different synth. The code is below and you can hear it on soundcloud

```ruby
#Carol_of_the_Bells.rb
#coded for Sonic Pi by Robin Newman, Dec 22 2020

use_bpm 2*78 #twice 78rpm!! criterion for Monthly Challenge #3
s=0.95;r=0.1 #set sustain release fractions
pp=0.3;p=0.4;mf=0.6;f=0.8;ff=1 #defeine vol levels

with_fx :reverb,room: 0.8,mix: 0.8 do
  use_synth :beep #synth for top part
  with_fx :level ,amp: 1.3 do #most toop part relative to the others
    with_fx :level,amp: pp do |v1| #set initial volume
      set :v1,v1 #pointer to fx_level
      #control volume at times specified by "at" this part also has variable slide times

Hi,

Maybe 🙂

The last challenge didn’t receive any submissions so I stopped, but I’ve been busy with other stuff as well.

Do you have an idea for one?

Hum?

Something that just came to mind:

One sound.

Imagine having to use only one sound and stretch, slice, pitch to make something?

Could be neat.

I’ve got one which is from Allen Strange’s book ’ Electronic Music: Systems, Techniques and Control’. It’s a sequencing score written by [Daniel Goode](http://www.composers21.com/compdocs/gooded.htm) for his 1975 piece ‘Faust Crosses the Raritan somewhere in West Africa and finds himself back home, somewhere south of the Reich’. The image contains the score based instructions.

 ![Ableton UG Instruction 1](https://europe1.discourse-cdn.com/flex017/uploads/sonic_pi/original/2X/5/5cbebc88a3021efc0054574b9331ead3b0ca18fc.jpeg)

I use this sometimes in the Ableton user group to approach sequencing from a different perspective.  
Looking forward to hearing and seeing different implementations.

I’d recommend Strange’s book as being a really good source of ideas whether using modular, DAW or live coding, or any combination thereof.

Yes, I do like this idea, perhaps I’ll open this one as challenge #6 for September 👍
