StompShare is a virtual effect shop app that recreates the effects display area of an instrument shop. This shop includes not only popular types of stomp box effects and rack mount effects, but it also offers guitar amp models and emulations of classic effects that can no longer be found new, for example. You can easily audition and even try effects before buying the ones that you like by connecting an MS-100BT hardware multistomp effector and an iOS device by Bluetooth. Then, you can add purchased effects to your MS-100BT and use them like any other hardware effect. We plan to continue adding even more variety of effects to StompShare in the future. ■Current StompShare provides 71 Effects and 23 Amps, total 94. -For Bass 22 effects, 9 amps -For Guitar 49 effects, 14 amps Features ■Connects easily using Bluetooth -Use Bluetooth to connect the iOS device and the MS-100BT without cables. ■Zoom in and out on effects -Double tap, pinch out and pinch in to zoom in and out. ■Select effects by category -Effects are categorized so you can easily find the ones you want. 5 categories Dynamics/Filter Overdrive/Distortion Amplifiers Modulation/SFX Delay/Reverb -You can also choose to view just the newest releases or all the effects at once. ■Explanations for all effects -An explanation for each effect includes information about the effect it models and the tones it can create. ■Audition demo sounds -Listen to demo sounds of every effect in the shop. -Turn the effect on and off while auditioning it. ■Effect trials -Write the effect to an MS-100BT pedal and use it to adjust parameters as you try playing with it. -You can also use the trial effect in combination with other effects already in your unit.
