hi guys thanks for the opinions, your reviews are of great encouragement to me. ok, let me clear some of the questions first- software and source code actually i was using FLASH to build the whole scene and graphics, and all the timing part are using Action Script 2.0. learning AS2.0 is far more easier than learning Visual C(i think ...), later i will make the source code available the timing problem there is one lacking point of the AS2.0 - the minimum time step is not exactly fixed, AS2.0 is embeded in the FLASH so, it is associated with the minimum time frame of the flash movie. i set the movie time frame to be 120f/s, which means minimum time step is around 8ms. so the biggest time error should be 4ms. if speed is 280bpm, then there will be around 2% mistake. but actually when the PC is busy, the time frame rate will drop and the timing error some times up to 10% probably, this is quite noticeable. so, the faster tempo, the more timing error. i tested at speed below 180 it should be working fine. and another thing i still haven't figure out is that the first beat always takes longer time. i guess it take time to load the scripts ....maybe the sound the sound formats are using both windows wave and mp3. so if pc can't decode the mp3(maybe) the sound will be missing. if i try using totally wave format then it should be better(but larger size). i am still considering making the volume adjustable and more sound effect to choose from. ---------------------------------------------------------------------------------------- hi ron, thank you for the nice comments, i have totally no idea about VB(plus the software is expensive and huge), anyhow perhaps VB should be more accurate in time dividing? the wave file i use windows recorder to record and edit, tried countless times then finally got a better timing. the wave is only 18ms~30ms long( the timing problem should be originated from here!!!!), so they are short enough for one beat. hi cheston, how are you lately? sorry long time haven't contact you, last month i was just back from phuket, i was so darn lucky man. so how's everything going? i listened all your recordings from the website, very good, you are really talented : ) steven
