Hello group, i´m trying to control Reaktor 2.3.3 MAC via external MIDI-Clock (Akai MPC 2000 ). As an interface i use the MT4 with OMS 2.3.8. My problem is, that the tempo isn´t recognized properly. The tempo in Reaktor slows down permanently. Let´s say the tempo of the sequencer is 160 bpm. Reaktor starts at about half of the tempo (80 bpm) and from that point permanently slows down, so that after a few seconds it ends up with 50 bpm. I need this for live-performances where an Akai MPC 2000 is clockmaster and Reaktor is slave. in the past i managed this with a midisport 2x2 interface. to reach better timing with LOGIC, i switched over to the MT4 (which works flawless within any application, except Reaktor). Powerbook G3 Pismo (latest Firmware) Mac OS 9.1 OMS 2.3.8 Logic Audio Platinum 4.7.2 Reaktor 2.3.3 thanks in advance for your answers jotka

You mean Reaktor worked with the Midisport, but does not with the MT4? -- Beste Gruesse - best regards, Michael Haydn EMAGIC Soft- und Hardware GmbH SoundDiver Group Executive Logic Audio Developer Unitor8 Control Project Manager

So at least i´m able to play the Reaktorsynthesizers with a keyboard (without any noticable latenzy). When i control Reaktor from within LAPM, the tempo is acurate and Reaktor even follows the tempochanges - so it´s not a Logic problem. The only problem is transmitting an external (MPC 2000) MIDIclock- signal to Reaktor. In this situation Reaktor starts with half of the tempo (MPC 2000 sends 160 bpm and Reaktor starts at 80 bpm and permanently slows down). So i guess its a problem between the MT4 and OMS (which i have to use to get the MT4 recogniced by Reaktor). I also posted this message on the Reaktor-list and got response from another user who has the same problem.

I just checked the code of the OMS driver. All realtime bytes are simply forwarded to OMS, without any processing. Hard to say what Reaktor actually receives. Does it have a MIDI monitor? -- Beste Gruesse - best regards, Michael Haydn EMAGIC Soft- und Hardware GmbH SoundDiver Group Executive Logic Audio Developer Unitor8 Control Project Manager

Thanks a lot for your answers! Reaktor only has a led for MIDI-in-detection and one for MIDI-out- detection. As i mentioned before, Reaktor receives perfect MIDI-timing when it´s loaded as an AudioInstrument within LAMP. The problem only occurs when i use Reaktor in standalone mode. As version 3 of Reaktor/Mac will be released within the next few days (that´s what Daniel Lieberberg told me on the sonar festival), i hope that this update will solve my problem.

Have you set the Midi input input to the port where you also recieve Midi? Try setting the port to *MT4*. Does this work better? Please let me know. Best Ray
