I am helping some friends make their first PD sound installation. They want 25 channels simultaneously running prerecorded samples and have a limited budget and as yet own no equipment. I use the presonus firepod external card in my work which could work with a single cpu chaining 3-4 of firepods together for their project but I doubt their budget can support buying so many of them. For amps we could build 25 simple chip amps with op amp ICs to keep costs down but those that I have built in the past are useful for low volume only. If anyone has other hardware configurations and amplifier schematics that they use I would be grateful for suggestions.
thanks
Greg
