HardSID Mac OS X Blog http://osx.hardsid.com Developing HardSID software for Mac OS X Sat, 15 Mar 2008 13:45:40 +0000 http://wordpress.org/?v=2.3.3 en The first sounds on OS X http://osx.hardsid.com/2008/03/15/the-first-sounds-on-os-x/ http://osx.hardsid.com/2008/03/15/the-first-sounds-on-os-x/#comments Sat, 15 Mar 2008 13:44:01 +0000 TS http://osx.hardsid.com/2008/03/15/the-first-sounds-on-os-x/ I’ve been working very hard in the past ~two weeks on the HardSID 4U Audio Unit. Today is the day when I could first play with the HardSID 4U in Logic using a MIDI keyboard. All of the basic things like voice allocation (mono, poly, unision), arpeggio modes, oscillator parameters, filter parameters, adsr parameters, detune, portamento, etc… seem to work. It can run in up to four instances (one for each SID) and one instance has 83 parameters already. Check out the huge scrollbar on the generic view! More advanced things like modulation matrix/table editor for every oscillator are missing yet of course, but I’m happy with the current state. When all of the more advanced features will be implemented/ported, I’ll do the custom GUI for it (to make it to look as nice as the Windows VSTi). Wish me good luck! ;)

I’ll try to keep the AU code / UI code as general as possible, so I can hopefully embed the same thing in a VSTi.

As some of you may already now, we didn’t plan OS X related developments. ..but the release of the HardSID 4U made many Mac users to nag me about the lack of OS X support.

Well, you won! ;)

While my friend prepares the fist stock of HardSID 4Us to be ready for the release date in April, I’ve jumped into OS X development.

Check out the roadmap below for the aims/objectives and the current status. Note: This is a spare-time hobby project and it is powered only by passion, devotion and enthusiasm. Please show us your interest by subscribing to our HardSID Mac OS X mailing-list and for the RSS feed via Feedburner (at the top of the sidebar)! Your interest is the thing that keeps us spinning!

Developers:

If you are an AU (Audio Units) developer and you are interested in developing your own HardSID 4U AU using a core communication library provided by us, contact us privately (support a.t. hardsid d.o.t. com) and subscribe to the HardSID Mac OS X mailing-list to discuss with other developers.

Roadmap (stage 1/2):

  • Establishing basic communication between OS X and HardSID 4U (status: Done)
  • Establishing low latency isochronous kernel streaming and also testing the 8000Hz update rate by beep sample playback (status: Done; comment: very good result!)
  • Developing a basic test AU (Audio Unit) that plays simple low latency notes and low latency samples at 8000Hz update rate on the HS4U (status: in progress ~50%)

At this point we’ll be able to tell details about the core library to AU developers. If you plan to develop your own HS4U AU, contact us! (support a.t. hardsid d.o.t. com) Also subscribe to the HardSID Mac OS X mailing-list!

Roadmap (stage 2/2):

  • Further development of our own AU. (it won’t be a direct port of the Windows VSTi, but a re-implementation)
  • Consulting with other AU developers (if any contacts us) for helping them and testing their AUs.
  • SIDPlay2 modification to achieve cycle-accurate playback on a HardSID 4U (won’t be a big work)

Note: I’m developing and testing on Intel (+Leopard), so required modifications (byte swapping macros mainly) for PPC will be applied a bit later, as soon as possible.

I’ll post any bigger progress here, so subscribe to the feed if you’re interested.
