Sonic Pi Monthly Challenge #1

Martin · October 4, 2020, 3:58pm

sounds interesting though I can not enjoy the complete code. I get a

Runtime Error: [buffer 3, line 121] - NoMethodError
Thread death +--> :live_loop_melody
 undefined method `to_f' for (ring <SonicPi::Chord :Eb :m7 [3, 6, 10,13]):SonicPi::Core::RingVector
Did you mean?  to_s
               to_a

[...]

Not sure where this comes from. I am running SP 3.2.0 on Linux. Any idea?

nlb · October 4, 2020, 5:17pm

for me another error on spi 3.2.2 on ubuntu 18.04. Seems to be a error due to the code this time @jrm
i do not use your sample but one from my own library

r: [buffer 7, line 143] - RuntimeError
Thread death +--> :live_loop_guiro2
 Value of opt :finish must be a value between 0 and 1 inclusively, got -1.2905239197630656.

jrm · October 4, 2020, 8:26pm

Hello I’m running 3.2.2, line 121 is a sleep, and line below is a sample command. I’ve no idea why it’s not running on your machine.
I’ll record a destructive output (MP3) and post it tomorrow.

jrm · October 4, 2020, 8:31pm

Hi @nlb, probably that’s because you don’t use my sample. start and finish values are functions of the sample length.

binarysweets · October 4, 2020, 9:51pm

Works for me on 3.2.2 (Win 10)
Nice use of the sample.

We can use this to share the code and audio from each challenge:

robin.newman · October 6, 2020, 12:58pm

Here’s an offering using a randomly chosen sample from freesound.org
I looked at the onsets within the long sample and from them generated playable “synths”. I used 12 of the onset voices to play four part rounds of frere jaques, and concluded with the 13th onset playing a stonking loud low version of Frere Jaques. I added fx wobble to the rounds and gverb to the single version, with some overall roll of of high frequencies with fx lpf.
Hear it on Sound Cloud. Description has link to the code.

binarysweets · October 7, 2020, 3:51pm

@jrm and @robin.newman I’ve added your code to the github repo:

@jrm, Are you able to upload an audio file somewhere please, so I can add it to the audio README.md in the ‘Audio’ folder?

binarysweets · October 8, 2020, 2:34pm

Here is my submission
https://soundcloud.com/binarysweets/toad-mode-sonic-pi-monthly-challenge-1

Using this random sample: puti32.aiff

I made two versions - One using live loops to get a jam going and to play about with the sample. I then created a structured version to record and mix down.

Code is in the monthly challenge repo here

germanaalvarado · October 9, 2020, 7:51pm

It’s great idea!

soxsa · October 10, 2020, 1:59pm

Here is mine. The sample I got was the interior of a bus https://freesound.org/people/florianreichelt/sounds/456833/ which I thought might be rich pickings but turned out to be mostly white noise. So I looked at it in Audacity and tried to pick out the little bits where there was something to latch on to.

I ended up with what it felt like to be snoozing on a bus, both lulled and woken by repetitive and chaotic noises. Horrible really.

Still, it was a good exercise in exploring more of the filters. A lot of band pass filtering to get something like a note, and the vowel filter which has a similar effect.

loving this challenge …

I was having a play today & think I’ve discovered something strange about FX :eq… it seems to swamp everything… I’ve even put it at 0.01 & wrapped it in an FX :level at amp: 0.01 and it just swamps anything else out… (other live loops etc).

[edit] - just discovered (should have looked first) that high / low / mid are levels… not frequencies… doh.

Hi @philAwesomeTech, the challenge is to use a random sample from Freesound (link at the top of the thread)

binarysweets · October 17, 2020, 10:02am

Just 2 weeks left for this challenge.
Got some good submissions in already

enkid0 · October 19, 2020, 7:53pm

My submission is here (feel free to import it to your soundcloud, I can send you a mp3 if you wish):

Based on this sample from Katy T:

binarysweets · October 20, 2020, 8:57am

Youtube is fine. I’ve embedded your video at the top and added it to the audio links file in the repo. Can you share your code as well please, so I can also add that to the repo? Thanks
