  • Page 3: Thank You

    It’s a unique clone for sound and feeling of the famous Minipops7 as used throughout several parts of world renown music by Jean Michelle Jarre. The MiniP7 has been designed to mimic the ‘spirit’ of the Minipops7 as good as possible.

  • Page 11: Tuning The Minip7

    4.2. Tuning the MiniP7 A hidden software feature allows the instruments to be triggered by the rhythm select buttons. As there are 15 instruments and only 10 rhythm select buttons, the instruments have been split into two groups. One 8 instruments group in the upper rhythm bank and a 7 instruments group in the lower rhythm bank.

  • Page 12: White Noise Level

    Relative trimmer position White Noise Level 4.2.2. Frequencies Not all instruments of the MiniP7 need to be tuned at time of assembly. The following table provides the approximate frequencies of the tunable instruments to be tuned to. Using a frequency meter or audio analyzer on PC may be a quite big job to get the tuning done.

  • Page 13: Mounting The Front Panel

    After assembly of the Front Panel, it’s time to place the knobs. 4.3.3. Connecting the Power Supply. The MiniP7 has a selectable power supply to operate either under 12V or 15V conditions. Place both jumpers on the right side for 15V operation and on the left side for 12V operation.

  • Page 14: Playing The Minip7 (User's Manual)

    5.1. Stand Alone 5.1.1. Selecting and Deselecting Rhythms and Combinations The MiniP7 does not have a ‘program’ memory, so it can not recall its last used rhythm. Therefor the MiniP7 starts up without any rhythm selected. Tambourine, Guiro and Quijada are always active and can be played without any of the rhythms active.

  • Page 15: Using External Clock And Sync

    5.2. Using External Clock and Sync 5.2.1. Introduction to external clocking. The MiniP7 has been foreseen with two extra inputs to provide the capability to use external applied clocking and resetting/syncing. The MiniP7 internal system mimics the original’s internal clocking system which switches between 12 and 16 counts per measure depending on the selected rhythm.
