CSOUND VERSION 6.18 RELEASE NOTES

Mainly a bug-fixing release. Major new facility is MP3 (MPEG) audio
files are supported both for input and output in platforms where this is
supported by libsndfile.

– The Developers

USER-LEVEL CHANGES

New opcodes

scanmap reads internal state of scanu

elapsedcycles, elapsedtime, eventcycles, and eventtime. See under
“bugs fied” for detials.

New gen

Orchestra

Score

Options

Modified Opcodes and Gens

fix midi list printing to stdout part of the list.

Utilities

Frontends

Bugs Fixed

Fixed bug where fixed-point phase computation (in oscil family) was
incorrect resulting in slight freq deviations in very low freq cases.

Fixed bug where freeing instr 0 caused memory issues in new
compilations. Instr 0 is not freed until reset now.

Fixed a bug where opcode directory search was crashing Csound if HOME
variable not set.

Fixed pol2rect array size setting.

OSCsend, OSCsend_lo and OSClisten can now work with OSC messages
carrying no payload (as per spec and manual).

bug in sum fixed

‘pitchamd’ opcode causes segmentation fault (macOS) (#1599)

fixed crash on channel setting with empty channel name

bug in ftloadk fixed (#1611)

qnan works even when compiled with fast arithmetic

Fix the flanger opcode for sample-accurate mode, where the xdel input was
not being correctly offset.

elapsedcycles, elapsedtime, eventcycles, and eventtime introducd as
fixed versions of timek, times, timeinstk and timeinsts but return
the correct values instead of being one cycle late. This prserves
backward compatability

SYSTEM LEVEL CHANGES

System Changes

Fix for issue #1613:
Fixes the rtauhal module for all cases of multichannel output. Previously the
module would not work correctly with some devices.

Csound now supports MP3 files for input and output through libsndfile (version 1.1.0 and higher).

Translations

API

External Plugin Code

Platform Specific

Bela:

Many changes to Bela csound. See bela web site for details

MacOS:

Universal build for x86_64 and arm64, backward compatible to MacOS 10.9

Issue where the portaudio callback backend would fail to work in mono (e.g. laptop microphone) has been fixed.

WASM:

fix sampleRate for single-thread worklet.

Awesome. Thanks to all the developers.

Andy.Fillebrown · October 27, 2022, 4:25pm

Very excited about this release! Thank you!

ThinkError · October 27, 2022, 6:06pm

Oh, I’ve been waiting for this. Thank you.

Say… could that bug fix to the oscil family be one of the oldest bugs to be fixed in Csound…(and possibly the oldest in any software)?

Victor_Lazzarini · October 27, 2022, 7:48pm

Actually not so. That bug was introduced sometime in Csound 5, when we increased the precision of the fixed point maths (in some versions, not all). It went undetected for perhaps 15 years, and I only discovered because I used an extremely long period with an oscili and it went a bit over.

rory · October 27, 2022, 8:57pm

Hmm, any idea what was the oldest bug ever to be fixed in Csound?

Victor_Lazzarini · October 27, 2022, 9:06pm

Good question. I think many bugs end up in people’s pieces and we can’t fix them anymore. They become the proverbial feature.

The longest bug ever? This is quite a nice idea. It resonates.

luisantunespena · October 28, 2022, 9:19am

Thank you to the developers!

One more general question: when installing csound via homebrew, csound will be placed in /opt/homebrew/bin/csound - I’m on macos 11.6. Are there any known problems because of that? Can the installation with brew cause some problems to find csound dependent libraries?

By the way, running brew upgrade csound is not possible to access to 6.18. I guess homebrew takes some time to update all new versions.

Best,

Luís

Victor’s right though, Csound’s backward compatibility means many bugs become a feature

Oeyvind · October 28, 2022, 9:48am

Should have been an exclamation mark. Of course! Mistype/autocorrect.

Any questions about brew should go to the brew team. We are not involved in maintaining or making any brew releases. I would expect them to pick up our upstream sources and update their scripts, but I don’t know anything more.

Michael_Gogins · October 28, 2022, 2:33pm

I just installed Csound 6.18 on my MacBook Pro M1 using Homebrew, and it runs.
