簡潔、直覺且功能完整的雙通道類比 Sample & Hold / Track & Hold 模組
S&H 是一款雙通道類比 Sample & Hold 模組,每個通道可在 Sample & Hold 與 Track & Hold 模式間切換,使用方式簡單卻擁有廣泛的應用可能性。無論是濾波器截止頻率 (filter cutoff)、VCO 音高 (pitch)、VCA 振幅 (amplitude) 或其他參數,只要需要隨機或循序的變化,都能透過 S&H 帶來豐富的調變效果。
S&H 的每個通道內建白噪聲產生器,並可接受外部訊號作為採樣來源,讓使用者能靈活選擇訊號來源進行創作。輸入範圍限制在 -6V 到 +10V,並具備輸入衰減器 (attenuator),能細緻調整調變的幅度,避免過度或不足的控制。
作為一款類比 Sample & Hold,S&H 在長時間電壓保持上會有輕微的電壓下墜 (voltage droop)。不同模組之間可能略有差異,且也會受到環境濕度等因素影響。在 Tenderfoot 位於台灣的測試環境中,平均量測結果為 每分鐘 0.025V,在多數情境下已足以穩定處理音高 CV 的採樣應用。
無論是要在旋律中加入隨機變化,還是為聲音設計提供不可預測的動態,S&H 都能以小巧的 4HP 寬度為系統增添靈活性。
