Hello everyone, I've released ddptools 0.8.5a, a set of command line programs to create, read and export audio from DDP images for CD audio. Due to the license of the official DDP specification these tools are not open source, but simple "freeware" at the moment, which I hope people will not mind too much. Details are found at http://ddp.andreasruge.de. The two main programs are: 1) cue2ddp - Create CD audio DDP 2.0 images from cue/wav images Features include: * track start, pause and index markers * ISRC, catalog number (UPC/EAN) * all track flags (pre-emphasis, copy permission, SCMS, 4ch) * all CD Text fields 2) ddpinfo - Display, check and export CD audio DDP images Features include: * display of all content from a DDP images (except the audio) * full PQ listing, CD Text fields * verification fo MD5 and CRC32 checksum files * export of audio as (Broadcast) Wave files including time stamp and track start positions as cue points * full DDP to cue/wav conversion, for burning or playing I'd like to encourage everyone interested to test the programs as hard as possible. I'm also planning on setting up a small test suite with real world examples of cue sheets and DDP images. As you might know cue/wave, cue/bin and DDP images come in many different flavors, some of which are really difficult to foresee. So, if you have software that generates either cue/wav or cue/bin images or DDP file sets, I'd like to ask you to prepare and send me a simple example image. Here are the instructions: * Any audio will do, but no more than 30 seconds please (~ 5 MB). Set a few tracks and use all options available, like pause markers, track indices, flags, ISRC, UPC, and especially CD Text. Fill all CD text fields offered and make sure at least one field has a double quote and a non-ASCII character inside. * Let me know which software you used to create the image * optionally: include a screen shot of the track/PQ/CD Text editor view * send the image as compressed email attachment Aside from that any feedback and ideas are welcome. Best Andreas

I don't think that you'll see just some puffy capacitors, OTOH IIRC your description doesn't lead to CEM chips, so I agree with Fons. For taking a look and using coolant spray you don't need knowledge and old gear usually is easy to open and to put together again. I won't reply to the replies regarding to Phasex and DSI, they're informing. Thank you! Regards, Ralf

First, every 8th (or was it 12th?) keys was stopping to produce sound (but they still sended MIDI signals), so I was able to use it as a MIDI controller (one of the best keyboards I ever used) and use another MIDI controller for triggering the jx-sounds. Then I could not do program changes, and then it stopped to make sounds - all this within two weeks. It does exist some Juno SW synths for MS Windows and Mac, but I won't use it. I'm usually pragmatic and do use both Mac and Windows for work (Linux is still main OS there also), but here, I run native Linux on everything and don't want to run another OS in my studio. > Better?

Well, I think I might try to get a new one again but also consider to see if I can make amSynt or even take my time to learn Yoshimi and see if it can do the job. Maybe a bright soul in this group is able to make a modelled JX or Juno with convolution? Jostein

Julien, those controllers are a good point. The KORG nanoKONTROL is very cheap, I own one since around 1 year, but never used it, anyway, it's known to work with Linux. If the OP has got some iThingy, there's a MIDI-Wi-Fi driver for Linux, unfortunately I still try to get Wi-Fi working on my machine. I assume that Wi-Fi for other Linux users does work ;D. FWIW, IIRC for mono Calf Monosynth and for poly Phasex can emulate some vintage synth, but still not the output of CEM chips. Hm? Mr. Smith still has got CEM chips, anyway, what happens if you need to replace such a chip? Full ACK Al. We only can buy second hand analog synth that are less old and that might still last for a while. If needed I would try to get something similar to a Minimoog out of my Oberheim Matrix-1000, but for doing this I need to get my Atari ST working again or I need to run Apple, Microsoft. Since my TG33 is borked, I hope we get some soft synth for vector control. The TG33 sounds without the vector control are less good than many soft synth, just the vector control adds a special quality that can't be produced with Linux soft synth, so theoretical it should be possible to get an TG33 emulator that is better than the original. The TG33 hasn't good samples and the FM synthesis isn't comparable to my DX7, but the TG33's FM synthesis might be comparable to the output of Hexter. James, Whysynth is very useful, but completely no help to get something Roland like. YMMV! An interesting and scary thread. Regards, Ralf

I've done a LOT of searching for a softsynth that will get one or two sounds of my Moogs. I've found some that sound "good." I get thinking that they are just about "it." And then I fire up one of the Moogs and compare, and find out just how different they are. One odd thing that I've consistently noticed over the past few years, is that if I find a good MiniMoog emulation, and match settings on it for one of my favorites on a Model D, is that, when listening to the emulation, it sounds very close. But, if I run each through a channel strip so I can directly A/B them, I find that the emulation is muddy and has no distinction. I have to roll a LOT of high end off of the real on to get the two channels to be even close. -- --- http://www.lateralforce.com My blog, with commentary on a variety of things, including audio, mixing, equipment, etc, is at: http://audioandmore.wordpress.com Staat heißt das kälteste aller kalten Ungeheuer.

If you just wish to get the sounds characteristics of some vintage synth and you should be willing to use Apple or Microsoft, than you'll find some proprietary soft synth there. I dunno if they will do something similar to the sound you need from the JX-8P. If you need the full CEM sound quality, than you definitively get stuck. For FM synth, Linux provides Hexter, the characteristics are close to a DX7, but far away to it's sound quality. I don't know any Linux synth emulator that has anything to do with an old analog synth. They are nice synth, but without the intensity of vintage analog synth. For Apple and Microsoft you'll find some analog synth emulations that are comparable to the difference between Hexter and a DX7. You won't get closer to vintage synth than that. Better? If you expect something completely new, than yes, you might find something better, but if you expect something that sounds like vintage synth, than all soft synth are less good, far away from the originals. There isn't a voodoo soft synth, they all sound similar to the soft synth you already tested. Regards, Ralf

No soft synth will reach the sound of CEM microchips or Yamaha FM synthesis. We get stuck if our old synth get broken. Regards, Ralf

/dev/rtc permissions on Debian

by rosea.grammostola

Hi, cannot set tick on /dev/rtc permission denied How important is it to solve this? It seems /dev/rtc is not in the Debian kernel, are there (lowlatency / RT) kernels for Debian with this feature included? Regards, \r

System check

Hi, Got some JACK crashes with Oomidi and Linuxsampler running. http://fpaste.org/az62/ Not to solve this particular problem directly, but just to check my system, comments are welcome ;) I don't have the snd-hrtimer loaded, is it needed?

Laborejo Release 0.1 Announcement

by Nils

Laborejo, Esperanto for "Workshop", is used to craft music through notation. It is a Lilypond GUI frontend, a MIDI creator and finally a tool collection to inspire and help you compose. It works by reducing music-redundancy and by seperating layout and data. Don't worry about the layout, just concentrate on the music. Screenshot (Laborejo and Lilypond, side by side): http://www.laborejo.org/images/screenshots/2012-01-31-223820_3840x1080_scro… This is the first release, version number 0.1 Download: https://github.com/nilsgey/Laborejo/tarball/0.1 Dependencies: http://www.laborejo.org/documentation There are too many features to mention them all and too many missing features and bugs to warn you. Most important known problems: * This is Alpha Grade Software. Don't use for long-term work. However, the produced midis and PDFs will last forever. * Performance can get bad very quickly if you use Containers. * There is no built-in sophisticated midi player/jack midi output yet. You have to export midi files. * Documentation is nearly non-existent. Have fun, it would be nice to hear from you!
