I'm looking for something that would have a variety of different tones to play for different alarms. Like an alarm for a power outage, flood waters, high winds, temperature, and other related types of warnings. I'm used to a basic stamp (freqout) where I can customize my sounds. I'm thinking of using one like a sound card and using the pulsin command to figure out what type of alarm to do, but I'd rather still just do it all within the RC.
