If you are controlling the experiment with a computer, you may find it a lot simpler to generate stimuli with the sound card. You can use my Daqarta for Windows software (free for signal generation uses) to generate signals in real-time. It can produce a broad range of waveforms (inlcuding arbitrary ones you define) and modulation types, and you can create extremely complex signals by using signals as modulators for other signals. Let me know if you want advice about applying Daqarta to your particular needs.
