Dear all, first of all I wish to thank all those who replied to my message. I received more or less 30 messages! This enthusiasm and will to share knowledge make me "feel good"! Again thank you so much. I tried to summarize the different solutions below grouped in different "categories", in case this may help someone else in the future. I still have to make a definite choice, but after discovering that onset extraction of tapping on a mic is mostly automatic, I may choose this way (ie recording both playback and tapping on the same file, left & right), although the NanoPad might be more fun for kids. very best regards daniele "Psychological solutions": software for presenting stimuli and recording using a mouse or keyboard. - DMDX, free software for stimuli presentation: http://www.u.arizona.edu/~kforster/dmdx/dmdx.htm - Psyscope X. It is freeware. http://psy.ck.sissa.it/ It's Mac-only, but has good timing accuracy and fairly easy to use. - Impromptu 1.21 (free MAC Scheme program language with easy access to sound, graphics and MIDI) and a Korg NanoPad "Classical solutions" - MaxMSP patch http://www.eecs.qmul.ac.uk/~andrewr/software/BeatAnnotator.zip (Mac version) Tap along on a mic or MIDI, analyzes and saves taps to txt file - MatTap:Matlab toolbox http://symonlab.org/mattap Requires Matlab and a data acquisition card compatible with the Data Acquisition Matlab toolbox http://sine.ni.com/nips/cds/view/p/lang/en/nid/201986 "Audio solutions": Using a microphone as the sensor, Playback of the stimulus and recording Better to record both output (metronome or music) and input (mic) as L&R channels in a stereo file. - PD (http://puredata.info/). Free - Daqarta for Windows (Shareware, 1 month) - Audacity, Free, can play and record, plus automatic extraction of taps to txt file Alternative to microphone: tap a button that makes or breaks a simple electrical circuit. The resulting signal could then be recorded through the sound-card as if it was a sound signal on the second stereo channel. "Hybrid solutions": audio software recording the mouse, keyboard or MIDI - Transcribe (http://www.seventhstring.com/) play a file and set markers by use of mouse/keys (Shareware, 1 month, multiplatform) - Sonic Visualiser (free, multiplatform) Can playback and record via keyboard or MIDI Export taps as txt file. "Getting rid of the computer solution" - Arduino (http://www.arduino.cc/). It contains a number of A/D converters as well as TTL inputs/outputs as well as a microcomputer. It can therefore be programmed to operate in real-time as a standalone, independent of any personal computer you need for the control and programming interfacing. It requires programming to perform a tapping experiment
