Hey Benno, I noticed that you where using one of those. Is that a mini-itx board in anycase? Me and my brother have been thinking about making a soundmodule with LinuxSampler and a mini-itx board. Though we where wondering how RT capable the platform was. If it's a mini-itx board you are using I guess that it works :) What about the built-in soundcard, know anything about it? Thinking about using one of those: http://www.mini-box.com/m100.htm /Robert |

Anyway, the actual quality depends a great > deal on the analog cirquitry on the board, Yes, I think the sound quality would be good enough at the moment. I was more thinking in the lines of RT capabilities. I've heard discouraging stories of badly functioning ac97 cards/drivers with ALSA. The problem with the mini-box solution is that there is no possibility of connecting any other soundcard, it won't fit in the box ;) USB is a possibility, but I'd rather not go there...

Yes, that's true, a way out if the analog-outs suck. :) /Robert |

Hi, yesterday I committed sustain pedal support in CVS (notes simply add up so you can max out polyphony if you keep hitting the same key with the sustain pedal pressed). If you max out the polyphony a crash is almost certain (due some missing checks in the LS code, probably Christian's fault :-) ). Now on the console you see a voice and stream counter that is updated in real time. Below responding to Robert's C3 questions: Scrive Robert Jonsson <rob...@da...>: > > The use case is actually very specific in our case.

For mini-itx hardware I suggest you to use the cases from Cubid: in particular the Cubid 2699R http://linitx.com/shop/product_info.php/cPath/8/products_id/155 83 EUR+ VAT The fastest VIA C3 Mainboard you can get is the 1GHz Nehemiah use this and not the slower ones because even the 1GHz is slow, so a 600-800MHz box will probably be too slow to achieve decent polyphony http://linitx.com/shop/product_info.php/cPath/12/products_id/207 137 EUR + VAT With these two things all you need is a DDR266+ DIMM RAM Module (the mainboard has only one RAM slot so chose the right size, I would say go with the 512MB to allow loading large samples since RAM is not that expensive these days). (512MB about 100 EUR) and a standard IDE HD. (I'd suggest a Maxtor :-) ) The cool thing of the Cubid case is that it has room for 1 PCI expansion card this means you can use a different audio card if the internal VIA audio sucks too much (it does indeed :-) ). I'd suggest you a cheap C-Media PCI card with dual stereo out and builtin MPU MIDI port (so for your MIDI-in you just need a cable, no USB MIDI in needed). Or alternatively use a card 24bit card like those from Terratec, about 100 EUR AFAIK * for example according to the alsa soundcards page http://www.alsa-project.org/alsa-doc/ the Terratec Aureon 7.1 Space supports: Aureon 7.1 Space The ultimate quality in sound * 8 (7.1) separate Speaker Outputs * Uncompromising 24 Bit / 96 kHz Playback and Recording * Digital In/Out, Optical 24 Bit / 96 kHz * A3D, EAX 1.0 and EAX 2.0 Support http://productsen.terratec.net/modules.php?op=modload&name=News&file=article&sid=149&mode=thread&order=0&thold=0 based on the Envy24HT Not sure if this card works well but I have M-Audio Delta cards based on the envy24 and the alsa support is excellent. (low latency works well). > > > > > > Though we where wondering how RT capable the platform was.

No need for RT Linux etc. I have a VIA C3 CPU (although in a different kind of mainboard, not soldered on the board) and the latency with a cmedia PCI (with the right lowlatency kernel) is as low as 3msec. (It's where I currently test LS :-) ). > > > > What about the built-in soundcard, know anything about it? > > > > It's an AC'97 chip with 18 bit full duplex I/O, but I can't seem to > > find any detailed specs.

Better avoid USB if you want good note-on MIDI response. See above :-) > > > unless you use the digital > > I/O and external converters. > Yes, that's true, a way out if the analog-outs suck. :) BTW: I already ordered stuff from linitx.com: fast delivery, good prices, good selection for VIA embedded stuff (for example they sell cheap compact flash to IDE adapters so you can put in a CF card and boot off that card like it were an IDE disk). At the ISP I work for we ordered a few (Nehemiah C3 + Cubid 2699R cases) because we are building some special network appliances for internal Hotel TVs. I think your LS drumkit expander would be quite a nice case study to show the general audience that LS can actually be used in a professional and live enviroment (of course when it will be stable and somewhat finished, not this developer version). Robert, as you have seen the above prices are not high compared to traditional hardware. (mainboards, CPUs). Yes the case is a bit more expensive than a traditional case but it's the price you pay for reduced size, fanless power supply unit, the C3 is a bit slow but I think it is more than enough for your purpose. cheers, Benno http://www.linuxsampler.org ------------------------------------------------- This mail sent through http://www.gardena.net |

A question to Robert (and others): you said you want to build this LS drumkit expander. Nice, but the question is: what's the price of MIDI drumpads ? Does it pay off to buy MIDI drumpads (how much do they cost?) compared to traditional analogue drumkits ? I'm not an expert here, so I might talking nonsense that's why I'm asking :-) What are the advantages of using a MIDI drumkit ? Price ? Easy switching of sounds (eg switching from a rock drumkit to a jazz drumkit, to an electronic drumkit etc), possibility of recording the events ? Possibility to use the sampler module to provide not only drumkit voices but an additional instrument like eg. piano too. (given enough CPU power) ? Just curious :-) If you build the LS expander we want pics/videos/audio demos of a band playing it live to put on the LS site :-) cheers, Benno http://www.linuxsampler.org ------------------------------------------------- This mail sent through http://www.gardena.net |

It has 12 drum pad inputs and produces MIDI output. It has a lot of built in sounds which I seldom use. I got a used 6-pad drumKat, an older funky square design, for about $150 I think. One of the guys on the Pro Tools site at DigiDesign offered it to me privately. It's a gas to play around with this stuff, and even though I'm no drummer I can usually get much better patterns this way than programming MIDI by hand in Pro Tools. The down side is I've got these big cables laying around whenever I hook this stuff up, so it's ugly and I trip a lot, but it's fun. - Mark |

I think this is what you are looking for: Roland TMC6 Trigger to MIDI Converter, 6 drumpad trigger inputs, one midi out http://www.zzounds.com/item--ROLTMC6 Cost: $239 The solution proposed by Robert is IMHO too messy because it requires lots of inputs and doing it yourself is a bit of a mess and you risk to get not the same good trigger to MIDI-velocity quality and trigger speed as with this device. Robert, start buying the hardware pieces, the LS site is waiting for the pics, videos and audio demos you promised :-) PS: To Robert, Mark and others, when you press reply all on your mail application please remove the name of the sender (in particular mine :-) ) because the sender always gets two mails if you don't do that.
