It's five months later now, and the LFO module still hasn't been released, and the MIDI/CV/USB modules still aren't available in Britain, and there is still no indication of any new synth modules that might come after the LFO. The only thing is your mention of a multi-effects bit - I'm sorry, but a multi-effects unit seems very much like "let's just do this and get it over with", because obviously it is not going to be as good as separate bits for each effect. It just seems like the future of the synth range is bleak. Are we ever going to get the modules needed to make a fully-featured synth?
Today LB sent out an email advertising the synth kit. I am surprised, given that the kit hasn't expanded since its original release. MIDI and CV are a major thing, sure, but there aren't any new modules to actually affect the sound that is produced. The whole thing seems like such a wasted opportunity. LB could be the best way for people to make modular synthesisers, yet it is limited to the most basic synth capabilities.
We need far more modules (chorus, LFO, sine wave, triangle wave, PWM, high-pass filter...) and the modules need to have more flexible connectivity so that, for example, you can modulate a filter with an envelope (and I mean either the cutoff OR the peak). This is the sort of stuff that could be done. I don't understand why LB seem to have so little interest in doing it.
To be clear, I do understand that everything takes time. It is the apparent disinterest of LB that saddens me. I can understand no new modules appearing (yet), but I can't understand the lack of news.
Here's one module you could make that would bring loads of customers to LittleBits: a formant filter. These are rare and expensive. If you made a formant filter module and priced it at $40, somebody could do formant filtering for $82. That's the power bit, the microphone (audio in) bit, the formant filter bit and the speaker (audio out) bit. All for $82. The cheapest formant filter I can find is $229. Do you really think people wouldn't go for the much cheaper LB option, even if they had never heard of LB before and didn't have any other LB modules? I think they would. It baffles me that LB aren't seeing the potential market here and really going for it.
Another one would be that miniature valve technology that Korg have acquired. Make a valve distortion bit and a valve oscillator bit. They'll be the cheapest way for people to do these things, and they will sell.
You have a fantastic opportunity here with the synth range. For God's sake, don't throw it away.
